3 Description

This device is a digitally controlled analog switch

that utilizes silicon-gate CMOS technology to achieve

operating speeds similar to LSTTL, with the low power

consumption of standard CMOS integrated circuits.

This analog multiplexer/demultiplexer controls analog

voltages that may vary across the voltage supply

range (for example, VCC to VEE). These bidirectional

switches allow any analog input to be used as an

output and vice versa. The switches have low ON

resistance and low OFF leakages. In addition, the

device has an enable control (E) that, when high,

disables all switches to their OFF state.
