Low-Voltage, Single and Dual Supply,
Quad SPST, High Performance Analog
Switches
Features
The Intersil ISL43143–ISL43145 devices are CMOS,
precision, quad SPST analog switches designed to operate
from a single +2V to +12V supply or from a 2V to 6V supply.
Targeted applications include battery powered equipment that
benefit from the devices’ low power consumption (<1W), low
leakage currents (5nA max), and fast switching speeds
(tON = 52ns, tOFF = 40ns). A 5 maximum RON flatness
ensures signal fidelity, while channel-to-channel mismatch is
guaranteed to be less than 2.
• Four Separately Controlled SPST Switches
The ISL43143/ISL43144/ISL43145 are quad single-pole/
single-throw (SPST) devices. The ISL43143 has four normally
closed (NC) switches; the ISL43144 has four normally open
(NO) switches; the ISL43145 has two NO and two NC
switches and can be used as a dual SPDT, or a dual 2:1
multiplexer.
Table 1 summarizes the performance of this family.

NOTE:
2. Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and
100% matte tin plate termination finish, which are RoHS
compliant and compatible with both SnPb and Pb-free soldering

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
3. Signals on NC, NO, COM, or IN exceeding V+ or V- are clamped by internal diodes. Limit forward diode current to maximum current ratings.
4. JA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
5. JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See
Tech Brief TB379 and Tech Brief TB389.

NOTES:
6. VIN = Input voltage to perform proper function.
7. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
8. Leakage parameter is 100% tested at high temp, and guaranteed by correlation at 25°C.
9. Flatness is defined as the delta between the maximum and minimum RON values over the specified voltage range.
10. Between any two switches.

Detailed Description
Power-Supply Considerations
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 (18) and high speed
switching (tON = 52ns, tOFF = 40ns). The devices are
especially well suited for portable battery powered
equipment thanks to the low operating supply voltage (2V),
low power consumption (1W), low leakage currents (5nA
max). High frequency applications also benefit from the wide
bandwidth, and the very high OFF isolation and crosstalk
rejection.
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.
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.
Logic inputs can easily be protected by adding a 1k
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.
Adding a series resistor to the switch input defeats the
purpose of using a low RON switch, so two small signal
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.

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.
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 especially RON - are strong functions of both supplies.
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 VIH level is about 2.8V, so
for best results use a logic family the provides a VOH greater
than 3V.
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 10A of
current (see Figure 18 for VIN = 3V). Similiar devices of
competitors can draw 8 times this amount of current.
High-Frequency Performance
VNO or NC
VCOM
In 5systems, signal response is reasonably flat even past
200MHz (see Figure 19). Figure 19 also illustrates that the
frequency response is very consistent over a wide V+ range,
and for varying analog signal levels.
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
V-
FIGURE 8. OVERVOLTAGE PROTECTION

FN6037.4
August 31, 2015
ISL43143, ISL43144, ISL43145
Crosstalk rejection provided by this family. At 10MHz, OFF
isolation is about 50dB in 5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-.
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-signalpath 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.
