ISL43112, ISL43113

Low-Voltage, Dual Supply, SPST, High

Performance Analog Switches

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 (250

µW), 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..
