Features
• Fully Specified at V = ±5V and ±3.3V for 10% Tolerances
S
The Intersil ISL43112 and ISL43113 are precision, high
performance analog switches designed to operate from
±1.5V to ±6V supplies. These devices are fully specified for
10% tolerance ±5V and ±3.3V supplies, and feature supply
and leakage currents much lower than those of other single
SPST switches. Turn-on and turn-off times are also
improved.

Targeted applications include battery powered equipment
that benefit from the devices’ low power consumption
(250µW), sub-nanoamp leakage currents, and fast switching
speeds
(tON = 40ns, tOFF = 25ns). The small SOT-23 packages,
and timing that delivers break-before-make operation, make
this family ideal for custom multiplexer applications.
Additionally, excellent RON flatness maintains signal fidelity
over the whole input range, while micro packaging alleviates
board space limitations. All these benefits combine to make
Intersil’s newest line of low-voltage switches ideal solutions
for “Next Generation” designs.

The ISL4311X are single-pole/single-throw (SPST) switches,
with the ISL43112 being normally open (NO), and the
ISL43113 being normally closed (NC).
Table 1 summarizes the performance of this family. For single
supply versions, see the ISL43110/11 datasheet..
