CD74HC4051-Q1,pdf(Analog Multi

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 (i.e., V_CC to V_EE). 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.
