描述 Description

The TPW4052 is dual SP4T analog switch suitable for use in

analog or digital multiplexer/demultiplexer applications. The

switch features three digital select inputs (S0, S1), eight

independent inputs/outputs (An, Bn), two common input/output

(A, B) and a digital enable input (/E). When /E is HIGH, the

switches are turned off.

The device is designed on an enhanced process that provides

lower power dissipation yet gives high switching speeds. These

devices can operate equally well as either multiplexers or demultiplexers and have an input range that extends to the

supplies. All channels exhibit break-before-make switching

action, preventing momentary shorting when switching

channels
