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
battery powered equipment, which benefit from low r_ON
resistance (0.8Ω), excellent r_ON flatness, and fast switching
speeds (t_ON = 24ns, t_OFF = 10ns). The digital logic input is
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.
