The Intersil ISL43210A device is a precision, bidirectional,

single SPDT analog switch designed to operate from a single

+2.7V to +15V supply. Targeted applications include

applications that require a +15V single supply such as

3D TV/Eyeware products and single supply +3.0V/+5V battery

powered equipment that benefit from the devices’ low power

consumption (5?W), low leakage currents (10nA max), and fast

switching speeds (tON = 28ns, tOFF = 20ns). 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 device may be used to “mux-in” additional functionality

while reducing ASIC design risk. It’s small package alleviates

board space limitations, making it an ideal solution.

The ISL43210A is a single committed SPDT, which is perfect for

use in 2-to-1 multiplexer applications.
