Description

PT233 is a feather touch function analog switch utilizing CMOS Technology. It features a mute output

to prevent “POP” Noise during the switching time, built-in analog switches and allows direct LED drive

for status Display and others through the built-in current buffer transistor. The Control System and

Analog Switch are operated by a single power supply. Pin assignments and application

circuit are optimized for easy PCB Layout as well as cost saving advantage.
