GENERAL DESCRIPTION
The ADG508F, ADG509F and ADG528F are CMOS analog
multiplexers, the ADG508F and ADG528F comprising eight
single channels and the ADG509F comprising four differential
channels. These multiplexers provide fault protection. Using a
series n-channel, p-channel, n-channel MOSFET structure,
both device and signal source protection is provided in the event
of an overvoltage or power loss. The multiplexer can withstand
continuous overvoltage inputs from –40 V to +55 V. During
fault conditions, the multiplexer input (or output) appears as an
open circuit and only a few nanoamperes of leakage current will
flow. This protects not only the multiplexer and the circuitry
driven by the multiplexer, but also protects the sensors or signal
sources that drive the multiplexer.
4. Fast Switching Times.
5. Break-Before-Make Switching.
Switches are guaranteed break-before-make so that input
signals are protected against momentary shorting.
6. Trench Isolation Eliminates Latch-up.
A dielectric trench separates the p and n-channel MOSFETs
thereby preventing latch-up.
ORDERING GUIDE

Package Option2
The ADG508F and ADG528F switch one of eight inputs to a
common output as determined by the 3-bit binary address lines
A0, A1 and A2. The ADG509F switches one of four differential
inputs to a common differential output as determined by the 2-
bit binary address lines A0 and A1. The ADG528F has on-chip
address and control latches that facilitate microprocessor inter-
facing. An EN input on each device is used to enable or disable
the device. When disabled, all channels are switched OFF.

Q-18
The ADG508F/ADG509F/ADG528F can withstand con-
tinuous voltage inputs from –40 V to +55 V. When a fault
occurs due to the power supplies being turned off, all the
channels are turned off and only a leakage current of a few
nanoamperes flows.

Figure 1 shows the timing sequence for latching the switch
address and enable inputs. The latches are level sensitive; there-
fore, while WR is held low, the latches are transparent and the
switches respond to the address and enable inputs. This input
data is latched on the rising edge of WR.
Figure 2 shows the Reset Pulsewidth, tRS, and the Reset Turn-
off Time, tOFF (RS).
Note: All digital input signals rise and fall times are measured
from 10% to 90% of 3 V. tR = tF = 20 ns.

*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability. Only one absolute
maximum rating may be applied at any one time.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although these devices feature proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

ADG508F/ADG509F/ADG528F
THEORY OF OPERATION
n-channel threshold voltage (VTN). When a voltage more nega-
tive than VSS is applied to the multiplexer, the p-channel
MOSFET will turn off since the analog input is more negative
than the difference between VSS and the p-channel threshold
voltage (VTP). Since VTN is nominally 1.5 V and VTP is typically
3 V, the analog input range to the multiplexer is limited to
–12 V to +13.5 V when a ±15 V power supply is used.
The ADG508F/ADG509F/ADG528F multiplexers are capable
of withstanding overvoltages from –40 V to +55 V, irrespective
of whether the power supplies are present or not. Each channel
of the multiplexer consists of an n-channel MOSFET, a p-
channel MOSFET and an n-channel MOSFET, connected in
series. When the analog input exceeds the power supplies, one
of the MOSFETs will switch off, limiting the current to sub-
microamp levels, thereby preventing the overvoltage from dam-
aging any circuitry following the multiplexer. Figure 12 illustrates
the channel architecture that enables these multiplexers to with-
stand continuous overvoltages.
When the power supplies are present but the channel is off,
again either the p-channel MOSFET or one of the n-channel
MOSFETs will turn off when an overvoltage occurs.
Finally, when the power supplies are off, the gate of each
MOSFET will be at ground. A negative overvoltage switches
on the first n-channel MOSFET but the bias produced by the
overvoltage causes the p-channel MOSFET to remain turned
off. With a positive overvoltage, the first MOSFET in the
series will remain off since the gate to source voltage applied to
this MOSFET is negative.
When an analog input of VSS + 3 V to VDD – 1.5 V is applied to
the ADG508F/ADG509F/ADG528F, the multiplexer behaves
as a standard multiplexer, with specifications similar to a stan-
dard multiplexer, for example, the on-resistance is 400 Ω maxi-
mum. However, when an overvoltage is applied to the device,
one of the three MOSFETs will turn off.
During fault conditions, the leakage current into and out of the
ADG508F/ADG509F/ADG528F is limited to a few microamps.
This protects the multiplexer and succeeding circuitry from over
stresses as well as protecting the signal sources which drive the
multiplexer. Also, the other channels of the multiplexer will be
undisturbed by the overvoltage and will continue to operate
normally.
Figures 12 to 15 show the conditions of the three MOSFETs for
the various overvoltage situations. When the analog input ap-
plied to an ON channel approaches the positive power supply
line, the n-channel MOSFET turns OFF since the voltage on
the analog input exceeds the difference between VDD and the
