+1.8V to +5.5V, 5Ω, Single SPDT Analog Switch
ISL54500
Features
• ON-resistance (r
)
The Intersil ISL54500 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 and fast switching speeds

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 ISL54500 is
offered in the 6 Ld 1.2mmx1.0mmx0.4mm pitch
µTDFN package, and 6 Ld SOT-23 package, alleviating
board space limitations.

The ISL54500 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.
Applications
• Battery powered, handheld, and portable
equipment
- Cellular/Mobile Phones
- Pagers
- Laptops, notebooks, palmtops
