The CD74HC4016 contains four independent 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.

Each switch has two input/output terminals (nY, nZ) and an active high enable input (nE). Current through the switch will not cause additional V_CC current provided the analog voltage is maintained between V_CC and GND.
