+1.8V to +5.5V, 2.5Ω, Single SPDT Analog Switch
ISL54503
The Intersil ISL54503 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 that benefit from low ON-resistance
(2.5Ω) and fast switching speeds (t_ON = 25ns,
t_OFF = 15ns). The digital logic input is 1.8V CMOS
compatible when using a single +3V 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 ISL54503 is offered in a 6 Ld
1.2mmx1.0mmx0.4mm pitch µTDFN package and a
6 Ld SOT-23 package, alleviating board space
limitations.
The ISL54503 is a committed SPDT that consist of one
normally open (NO) and one normally closed (NC)
switch. This configuration can also be used as a 2-to-1
multiplexer.
