Ultra Low ON-Resistance, +1.1V to +4.5V
Single Supply, SPST Analog Switches
The Intersil ISL43L110 and ISL43L111 devices are low
ON-resistance, low voltage, bidirectional, single pole/single
throw (SPST) analog switches designed to operate from a
single +1.1V to +4.5V supply. Targeted applications include
battery powered equipment that benefit from low RON
resistance, excellent RON flatness, and fast switching
speeds (tON = 8ns, tOFF = 5ns). The digital logic input is
1.8V CMOS compatible when using a single +3V supply.
Cell phones, for example, often face ASIC functionality
limitations. The number of analog input or GPIO pins may be
limited and digital geometries are not well suited to analog
switch performance. This family of parts may be used to
switch in additional functionality while reducing ASIC design
risk. The ISL43L11X are offered in a 5 lead SC70 package,
alleviating board space limitations.
The ISL43L110 has one normally open (NO) switch and
ISL43L111 has one normally closed (NC) switch.

Detailed Description
Supply Sequencing and Overvoltage Protection
The ISL43L110 and ISL43L111 are bidirectional, single
pole/single throw (SPST) analog switches. They offer
precise switching capability from a single +1.1V to 4.5V
supply with ultra low on-resistance and high speed
operation. With a single supply of 4.3V the typical onresistance is only 0.21, with a typical turn-on and turn-off
time of: tON = 8ns, tOFF = 5ns. The devices are especially
well suited for portable battery powered equipment due to its
low operating supply voltage (1.1V), low power consumption
(1.8W max), low leakage currents (200nA max), and the tiny
SC70 packaging.
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 GND (see
Figure 6). To prevent forward biasing these diodes, V+ must
be applied before any input signals, and the input signal
voltages must remain between V+ and GND.
The ISL43L110 is a normally open (NO) SPST analog
switch. The ISL43L111 is a normally closed (NC) SPST
analog switch.
If these conditions cannot be guaranteed, then precautions
must be implemented to prohibit the current and voltage at
the logic pin and signal pins from exceeding the maximum
ratings of the switch. The following two methods can be used
to provided additional protection to limit the current in the
event that the voltage at a signal pin or logic pin goes below
ground or above the V+ rail.
Logic inputs can be protected by adding a 1k resistor in
series with the input (see Figure 6). The resistor limits the
input current below the threshold that produces permanent

FN6130.1

ISL43L110, ISL43L111
damage, and the sub-microamp input current produces an
insignificant voltage drop during normal operation.
This method is not acceptable for the signal path inputs.
Adding a series resistor to the switch input defeats the
purpose of using a low RON switch. Connecting schottky
diodes to the signal pins as shown in Figure 6 will shunt the
fault current to the supply or to ground thereby protecting the
switch. These schottky diodes must be sized to handle the
expected fault current.
The digital input stages draw supply current whenever the
digital input voltage is not at one of the supply rails. Driving
the digital input signals from GND to V+ with a fast transition
time minimizes power dissipation.
In 50 systems, signal response is reasonably flat even past
100MHz (See Figure 16). The frequency response is very
consistent over a wide V+ range, and for varying analog
signal levels.

This switch family is 1.8V CMOS compatible (0.5V and 1.4V)
over a supply range of 2V to 3.6V (See Figure 15). At 3.6V
the VIH level is about 1.1V. This is still below the 1.8V CMOS
guaranteed high output minimum level of 1.4V, but noise
margin is reduced.

Power-Supply Considerations
The ISL43L11X construction is typical of most single supply
CMOS analog switches in that they have two supply pins: V+
and GND. V+ and GND drive the internal CMOS switches
and set their analog voltage limits. Unlike switches with a 4V
maximum supply voltage, the ISL43L11X 4.7V maximum
supply voltage provides plenty of room for the 10% tolerance
of 4.2V supplies, as well as room for overshoot and noise
spikes.
The minimum recommended supply voltage is 1.1V. 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 also power the internal logic and level shiftier.
The level shiftier converts the input logic levels to switched
V+ and GND signals to drive the analog switch gate
terminals.
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. Figure 17 details the high
Off Isolation rejection provided by this family. At 100kHz, Off
Isolation is about 65dB in 50 systems, decreasing
approximately 20dB per decade as frequency increases.
Higher load impedances decrease Off Isolation 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 GND. One of
these diodes conducts if any analog signal exceeds V+ or
GND.
Virtually all the analog leakage current comes from the ESD
diodes to V+ or GND. 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 GND 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 GND pins constitutes the analogsignal-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 V+ or GND.
This family of switches cannot be operated with bipolar
supplies, because the input switching point becomes
negative in this configuration.
