Switch
ISL43210A
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 (5µW), low leakage currents (10nA max), and fast
switching speeds (t_ON = 28ns, t_OFF = 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.
