FEATURES
DESCRIPTION
The TK15323M 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 TK15323M has
a mono-power supply and the input bias is a supply type
from outside. Because the distortion is very low, the
TK15323M fits various signals switching. It is best suited
for Hi-Fi devices. Operating voltage is wide, the circuit
plan is simple. The TK15323M is available in a small
plastic surface mount package (SSOP-12).
