ISL43112IB-T中文资料Intersil数据手册PDF规格书

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).
