ISL43L710, ISL43L711, ISL43L712

Ultra Low ON-Resistance, Single Supply,

Differential SPST Analog Switches

The Intersil ISL43L710, ISL43L711, ISL43L712 devices are

low ON-resistance, low voltage, bidirectional, precision,

differential single-pole/single-throw (SPST) analog switches

designed to operate from a single +1.65V to +3.6V supply.

Targeted applications include battery powered equipment

(0.12

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 ISL43L71X are offered in small form factor

packages, alleviating board space limitations.

The ISL43L710, ISL43L711, ISL43L712 are differential

single-pole/single-throw (SPST) devices. The ISL43L710

has two normally open (NO) switches; the ISL43L711 has

two normally closed (NC) switches; the ISL43L712 has one

normally open (NO) and one normally closed (NC) switch

and can be used as an SPDT. The ISL43L712 is equipped

with an inhibit pin to simultaneously open all signal paths.

Table 1 summarizes the performance of this family.
