The CD74HC4016MT is a single-pole single-throw (SPST) high speed logic quad bilateral CMOS Analog Switch 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 VCC current provided the analog voltage is maintained between VCC and GND.
