Power-Supply Considerations
Detailed Description
The ISL4314X construction is typical of most CMOS analog
switches, in that they have three supply pins: V+, V-, and
GND. V+ and V- drive the internal CMOS switches and set
their analog voltage limits, so there are no connections
between the analog signal path and GND. Unlike switches
with a 13V maximum supply voltage, the ISL4314X 15V
maximum supply voltage provides plenty of room for the
10% tolerance of 12V supplies (±6V or 12V single supply),
as well as room for overshoot and noise spikes.
The ISL43143–ISL43145 quad analog switches offer precise
switching capability from a bipolar ±2V to ±6V or a single 2V
to 12V supply with low on-resistance (18Ω) and high speed
switching (t
= 52ns, t = 40ns). The devices are
ON
OFF
especially well suited for portable battery powered
equipment thanks to the low operating supply voltage (2V),
low power consumption (1µW), low leakage currents (5nA
max). High frequency applications also benefit from the wide
bandwidth, and the very high OFF isolation and crosstalk
rejection.
This family of switches performs equally well when operated
with bipolar or single voltage supplies, and bipolar supplies
need not be symmetrical. The minimum recommended
supply voltage is 2V or ±2V. It is important to note that the
input signal range, switching times, and ON-resistance
degrade at lower supply voltages. Refer to the electrical
specification tables and Typical Performance Curves for
details.
Supply Sequencing And Overvoltage Protection
As with any CMOS device, proper power supply sequencing
is required to protect the device from excessive input
currents which might permanently damage the IC. All I/O
pins contain ESD protection diodes from the pin to V+ and to
V- (see Figure 8). To prevent forward biasing these diodes,
V+ and V- must be applied before any input signals, and
input signal voltages must remain between V+ and V-. If
these conditions cannot be guaranteed, then one of the
following two protection methods should be employed.
V+ and GND power the internal logic (thus setting the digital
switching point) and level shifters. The level shifters convert
the logic levels to switched V+ and V- signals to drive the
analog switch gate terminals, so switch parameters -
Logic inputs can easily be protected by adding a 1kΩ
resistor in series with the input (see Figure 8). The resistor
limits the input current below the threshold that produces
permanent damage, and the sub-microamp input current
produces an insignificant voltage drop during normal
operation.
especially R
- are strong functions of both supplies.
ON
Logic-Level Thresholds
V+ and GND power the internal logic stages, so V- has no
affect on logic thresholds. This switch family is TTL
compatible (0.8V and 2.4V) over a V+ supply range of 2.5V
to 10V (see Figure 17). At 12V the V level is about 2.8V,

purpose of using a low R
switch, so two small signal
ON
diodes can be added in series with the supply pins to provide
overvoltage protection for all pins (see Figure 8). These
additional diodes limit the analog signal from 1V below V+ to
1V above V-. The low leakage current performance is
unaffected by this approach, but the switch resistance may
increase, especially at low supply voltages.
The digital input stages draw supply current whenever the
digital input voltage is not at one of the supply rails (see
Figure 18). Driving the digital input signals from GND to V+
with a fast transition time minimizes power dissipation. The
ISL43143-ISL43145 switches have been designed to
minimize the supply current whenever the digital input
voltage is not driven to the supply rails (0V to V+). For
example driving the device with 3V logic while operating with
dual or single 5V supplies the device draws only 10µA of
current (see Figure 18 for VIN = 3V). Similiar devices of
competitors can draw 8 times this amount of current.

High-Frequency Performance
In 50Ω systems, signal response is reasonably flat even past

OPTIONAL PROTECTION
DIODE
An off switch acts like a capacitor and passes higher
frequencies with less attenuation, resulting in signal
feedthrough from a switch’s input to its output. OFF Isolation
is the resistance to this feedthrough, while Crosstalk
indicates the amount of feedthrough from one switch to
another. Figure 20 details the high OFF Isolation and

Crosstalk rejection provided by this family. At 10MHz, OFF
Virtually all the analog leakage current comes from the ESD
diodes to V+ or V-. Although the ESD diodes on a given
signal pin are identical and therefore fairly well balanced,
they are reverse biased differently. Each is biased by either
V+ or V- and the analog signal. This means their leakages
will vary as the signal varies. The difference in the two diode
leakages to the V+ and V- pins constitutes the analog-signal-
path leakage current. All analog leakage current flows
between each pin and one of the supply terminals, not to the
other switch terminal. This is why both sides of a given
switch can show leakage currents of the same or opposite
polarity. There is no connection between the analog signal
paths and GND.
isolation is about 50dB in 50Ω systems, decreasing
approximately 20dB per decade as frequency increases.
Higher load impedances decrease OFF Isolation and
Crosstalk rejection due to the voltage divider action of the
switch OFF impedance and the load impedance.
Leakage Considerations
Reverse ESD protection diodes are internally connected
between each analog-signal pin and both V+ and V-. One
of these diodes conducts if any analog signal exceeds V+
or V-.
