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 that benefit from low R_ON (0.16Ω), low power consumption (0.12μW) and fast switching speeds (t_ON = 13ns, t_OFF = 13ns).

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.
