Description

The Intersil ISL43L120, ISL43L121, ISL43L122 devices are low ON-resistance, low voltage, bidirectional, precision, dual 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 ISL43L12X are offered in an 8 Ld MSOP package, alleviating board space limitations.

The ISL43L120, ISL43L121, ISL43L122 are dual singlepole/ single-throw (SPST) devices. The ISL43L120 has two normally open (NO) switches; the ISL43L121 has two normally closed (NC) switches; the ISL43L122 has one normally open (NO) and one normally closed (NC) switch and can be used as an SPDT.
