74HC4066 single-throw analog switch

General description

The 74HC4066 is a quad single pole, single throw analog switch. Each switch features two input/output terminals (nY and nZ) and an active HIGH enable input (nE). When nE is LOW, the analog switch is turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

4066 is identical in pinout to the metal–gate CMOS MC14016 and MC14066. Each device has four independent switches. The device has been designed so that the ON resistances (RON) are much more linear over input voltage than RON of metal–gate CMOS analog switches. This device is identical in both function and pinout to the HC4016. The ON/OFF control inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. For analog switches with voltage–level translators, see the HC4316.
