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 de-multiplexer.

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.
