Overview
The 74HCT4066PW is a quad single-pole single-throw analog switch produced by Nexperia USA Inc. This integrated circuit is part of the 74HCT family, which operates with TTL (Transistor-Transistor Logic) input levels. Each switch in the 74HCT4066PW features two input/output terminals (nY and nZ) and an active HIGH enable input (nE). When the enable input (nE) is LOW, the analog switch is turned off. The device includes clamp diodes on the inputs, allowing the use of current limiting resistors to interface inputs to voltages in excess of VCC.
