High Speed CMOS Logic Analog Multiplexer / Demultiplexer, 16uA, 2V to 6V, DIP 16, - 

The CD74HC4052E is a 4-channel high speed CMOS differential Analogue Multiplexer/Demultiplexer, also known as digitally controlled analogue switch that uses silicon gate CMOS technology to achieve operating speeds similar to LSTTL with the low-power consumption of standard CMOS integrated circuits. This analogue multiplexer and demultiplexer control analogue voltages that may vary across the voltage supply range (for example, VCC to VEE). This multiplexer/demultiplexer is a bidirectional switch that allow any analogue input to be used as an output and vice versa. The switch has low ON resistance and low OFF leakages. In addition, the device has an enable control that, when high, disables the switch to OFF state.
