DESCRIPTION

The TK15321M is an Analog Switch IC that was developed

for audio frequency. Function is to select one output from

two inputs in a device that includes two circuits, and the

channel can be changed by low level. The TK15321M has

a mono-power supply and the input bias is a built-in type

(V

fits various signals switching. It is best suited for Hi-Fi

devices. Operating voltage is wide, the circuit plan is

simple. The TK15321M is available in a small plastic

surface mount package (SSOP-12).
