Low-Voltage, Dual Supply, SPST, High
Performance Analog Switches
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..
