+1.8V to +5.5V, 5Ω, Single SPST Analog Switches
ISL54501, ISL54502
Features
• ON-resistance (r
)
The Intersil ISL54501 and ISL54502 devices are low
ON-resistance, low voltage, bi-directional, single
pole/single throw (SPST) analog switches designed to
operate from a single +1.8V to +5.5V supply. Targeted
applications include battery powered equipment that

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.
