Ultra Low ON-Resistance, Low Voltage, Single
Supply, SPDT Analog Switch
ISL54053
The Intersil ISL54053 device is a low ON-resistance, low
voltage, bidirectional, single pole/double throw (SPDT)
analog switch designed to operate from a single +1.8V
to +5.5V supply. Targeted applications include battery
powered equipment which benefit from low r_ON (0.8Ω)
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 part may be
used to “mux-in” additional functionality while reducing
ASIC design risk. The ISL54053 is offered in the 6 Ld
1.2mmx1.0mmx0.5mm µTDFN and 6 Ld SOT-23
packages, alleviating board space limitations.
The ISL54053 is a committed SPDT that consists of one
normally open (NO) and one normally closed (NC)
switch. This configuration can also be used as a 2-to-1
multiplexer.
