The Intersil ISL54501 and ISL54502 devices are low
ON-resistance, low voltage, bidirectional, single pole/single
throw (SPST) analog switches designed to operate from a
single +1.8V to +5.5V supply. Targeted applications include

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 ISL54501, ISL54502 are offered in a 6 Ld
1.2mmx1.0mmx0.4mm pitch µTDFN package, alleviating
board space limitations.
