Quad 18V Pin Electronics Driver/Window
Comparator
Features
• Low Driver Output Resistance
- R Maximum: ISL55100A 7.0Ω
The ISL55100 is a Quad pin driver and window comparator
fabricated in a wide voltage CMOS process. It is designed
specifically for Test During Burn In (TDBI) applications,
where cost, functional density, and power are all at a
premium.
OUT
• 18V I/O Range
• 50MHz Operation
• 4 Channel Driver/Receiver Pairs with Per Pin Flexibility
• Dual Level - Per Pin - Input Thresholds
• Differential or Single Ended Digital Inputs
• User Defined Comparator Output Levels
• Low Channel to Channel Timing Skew
• Small Footprint (72 Ld QFN)
This IC incorporates four channels of programmable drivers
and window comparators into a small 72 Ld QFN package.
Each channel has independent driver levels, data, and high
impedance control. Each receiver has dual comparators
which provide high and low threshold levels.
The ISL55100 uses differential mode digital inputs, and can
therefore mate directly with LVDS or CML outputs. Single
ended logic families are handled by connecting one of the
digital input pins to an appropriate threshold voltage (e.g.,
1.4V for TTL compatibility). The comparator outputs are
single ended, and the output levels are user defined to mate
directly with any digital technology.
• Pb-Free Plus Anneal Available (RoHS Compliant)
Applications
• Burn In ATE
• Wafer Level Flash Memory Test
• LCD Panel Test
• Low Cost ATE
The 18V driver output and receiver input ranges allow this
device to interface directly with TTL, ECL, CMOS (3V, 5V,
and 7V), LVCMOS, and custom level circuitry, as well as the
high voltage (Super Voltage) level required for many special
test modes for Flash Devices.

Application Information
GND, or any supply voltage, won’t cause permanent damage,
but care must be taken to avoid longer duration short circuits.
If tolerable to the application, current limiting resistors can be
inserted in series with the QA(0-3) and QB(0-3) Outputs to
protect the receiver outputs from damage due to overcurrent
conditions.
The ISL55100 provides Quad pin drivers and Quad dual
level comparator receivers in a small footprint. The four
channels may be used as bidirectional or split channels.
Drivers have per channel level, data, and high impedance
controls, while comparators have per channel high and low
threshold levels.
Driver Features
Receiver Features
The drivers are single ended outputs featuring a wide
voltage range, an output stage capable of delivering 200mA
while providing a low out resistance and tri-state capability.
Additionally, the driver output can be toggled to drive one of
two user defined output levels High (VH) or Low (VL).
The receivers are four independent window comparators that
feature high output current capability, and user defined high
and low output levels to interface with a wide variety of logic
families. Each receiver, comprises two comparators and each
comparator has an independent threshold level input, making
it easy to implement window comparator functions. The CVA
and CVB pins set the threshold levels of the A and B
comparators respectively. COMP HIGH and COMP LOW set
all the comparator output levels, and COMP HIGH must be
more positive than COMP LOW. These two inputs are
unbuffered supply pins, so the sources driving these pins
must provide adequate current for the expected load. COMP
HIGH and COMP LOW typically connect to the power
supplies of the logic device driven by the comparator outputs.
The truth table for the receivers is given on page 3. Receiver
outputs are not tri-statable, and do not incorporate any on-chip
Driver waveforms are greatly affected by load
characteristics. The ISL55100 actually double bonds the
VH(0-3) and VL(0-3) supply pins for each channel. The
Driver Output Pins (DOUT(0-3)) are triple bonded. Multiple
bond wires help reduce the effects of Inductance between
the IC Die (Wafer) and the packaging. Also the QFN style of
packaging reduces inductance over other types of
packaging.
While the inductance of a bond wire might seem
insignificant, it can reduce high-frequency waveform fidelity.
So this should be borne in mind when doing PCB layout and

as possible and make sure scope measurements are made
properly. Often the inductance of a scope probe ground can
be the actual cause of the waveform distortion.

Current drain is directly proportional to Data Rate. This
option will help with Power Supply/Dissipation should heat
distribution become an issue.
There are sets of VH and VL pins designated for each Driver.
These are unbuffered analog inputs that determine the Drive
High (VH) and Drive Low (VL) Voltages that the drivers will
deliver. These inputs are double bonded to reduce
inductance and decrease AC Impedance.
Power Supply Bypassing and Printed Circuit
Board Layout
As with any high frequency device, good printed circuit
board layout is necessary for optimum performance. Ground
plane construction is highly recommended, lead lengths
should be as short as possible, and the power supply pins
must be well bypassed to reduce the risk of oscillation. For
Each VH and VL should be decoupled with 4.7µF and 0.1µF
capacitors to ground. If all four VH/VLs are bussed per
device then one 4.7µF can be used for multiple VH/VL pins.
Layouts should also accommodate the placement of
capacitance “across” VH and VL. So in additional to
decoupling the VH/VL pins to ground, they are also
decoupled to each other.

ground. This same capacitor combination should be placed
at each supply pin to ground if split supplies are to be used.
The ISL55100 uses differential mode digital inputs, and can
therefore mate directly with LVDS or CML outputs. Single
ended logic families are handled by connecting one of the
digital input pins to an appropriate threshold voltage (e.g.,
1.4V for TTL compatibility).
Power Dissipation Considerations
Specifying continuous data rates, driver loads and driver
level amplitudes are key in determining power supply
requirements as well as dissipation/cooling necessities.
Driver Output patterns also impact these needs. The faster
the pin activity, the greater the need to supply current and
remove heat.
LOSWING Circuit Option
The drivers include switchable circuitry that is optimized for
either low (VH-VL < 3V) or high output swings, and this
selection is accomplished via the LOSWING pin. Connecting

package is 23.0, 16.6 and 14.9 Deg C/W based on Airflows

1 under Thermal Information. With the high speed data rate
capability of the ISL55100, it is possible to exceed the 150°C
“absolute-maximum junction temperature” as operating
conditions and frequencies increase. Therefore, it is
important to calculate the maximum junction temperature for
the application to determine if operating conditions need to
be modified for the device to remain in the safe operating
area.

With LOSWING = V , the low swing circuitry activates

whenever VH < V + 5V, and the VH and VL currents

increase, so for the lowest power dissipation set LOSWING
= V only if the output swing (VH-VL) is less than 3V, and
EE
better than 10% overshoots are required.
For the best small signal performance, the VH/VL common
mode voltage [(VH + VL)/2] must be V + 1.5V. So if V

Driver and Receiver Overload Protection
The maximum power dissipation allowed in a package is
determined according to:
The ISL55100 is designed to provide minimum and balanced
Driver ROUT. Great care should be taken when making use
of the ISL55100 low ROUT drivers as there is no internal
protection. There is no short circuit protection built into either
the driver or the receiver/comparator outputs. Also there are
no junction temperature monitors or thermal shutdown
features.

supply voltage, plus the power in the IC due to the loads.
Power also depends on number of channels changing state,
frequency of operation. The extent of continuous active
pattern generation/reception will greatly effect dissipation
requirements.
Important Note: The ISL55100 package metal plane is
used for heat sinking of the device. It is electrically
connected to the negative supply potential (V ). If V

The power dissipation curves (Figure 16), provide a way to
see if the device will overheat. The maximum safe power
temperature vs operating frequency can be found graphically
in Figure 17. This graph is based on the package type Theta
JA ratings and actual current/wattage requirements of the
ISL55100 when driving a 1K load with a 6V High Level and a
0V Low Rail. The temperatures are indicated as calculated
junction temperature over the ambient temperature of the
user’s system. Plots indicate temperature change as
operating frequency increases. (The graph assumes
continuous operation.) The user should evaluate various
heat sink/cooling options in order to control the ambient
temperature part of the equation. This is especially true if the
users applications require continuos, high speed operation.

Power Supply Sequencing
The ISL55100 references every supply with respect to VEE.
Therefore apply VEE, then VCC followed by the VH,VL
busses, then the COMP High and Comp Low followed by the
CVA & CVB Supplies. Digital Inputs should be set with a
differential bias as soon as possible. In cases where V

Data Rates
Please note that the Frequency - MHz in Figures 16 and 17
contain two transitions within each period. A digital
application that requires a new test pattern every 50ns would
be running at a 20MHz Data Rate. Figure 18 reveals 100ns
period, in 10MHz frequency parlance, results in two 50ns
digital patterns.
The reader is cautioned against assuming the same
level of thermal performance in actual applications. A
careful inspection of conditions in your application
should be conducted. Great care must be taken to
