3 Description
The TS3A5223 is a high-speed 2-channel analog
switch with break-before-make and bi-directional
signal switching capability. The TS3A5223 can be
used as a dual 2:1 multiplexer or a 1:2 dual demultiplexer.
The TS3A5223 offers very low ON resistance, very
low THD, channel-to-channel crosstalk and very high
OFF isolation. These features make TS3A5223
suitable for application in Audio signal routing and
switching applications.
The TS3A5223 control logic supports 1 V – 3.6 V
CMOS logic levels. The logic interface allows direct
interface with a wide range of CPUs and
microcontrollers without increasing the current drawn
from supply (ICC) and thus lowering power
consumption.
