DESCRIPTION
The TS3A5223 is a high-speed dual 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 1.0V-3.6V
CMOS logic levels. The logic interface allows direct
interface with a wide range of CPUs and
microcontrollers without increasint the current drawn
from supply (ICC) and thus lowering power
consumption.
