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
CC
/ 2 V). Because the distortion is very low, the TK15321M
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).
