The CD74HC4067 and CD74HCT4067 devices are digitally controlled analog switches that use silicon-gate CMOS technology to achieve operating speeds similar to LSTTL, with the low power consumption of standard CMOS integrated circuits.
These analog multiplexers and demultiplexers control analog voltages that may vary across the voltage supply range. They are bidirectional switches, thus allowing any analog input to be used as an output and vice-versa. The switches have low on resistance and low off leakages. In addition, these devices have an enable control that, when high, disables all switches to their off state.
