ISL54051, ISL54052

Ultra Low ON-Resistance, Low Voltage,

Single Supply, Single SPST Analog

Switches

The Intersil ISL54051 and ISL54052 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

resistance (0.8

1.8V logic compatible when using a single +3.0V supply.

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

ISL54051 and the ISL54052 are offered in a 6 Ld

1.2mmx1.0mmx0.5mm µTDFN package, alleviating board

space limitations.

The ISL54051 has one normally open (NO) switch and

ISL54052 has one normally closed (NC) switch.
