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.
