74HC4066 Datasheet – Quadruple Bilateral Analog Switch
74HC4066 overview
The 74HC4066 is a Quadruple Bilateral Analog Switch made by Philips Electronics - NXP, supplied in these packages: SOIC, SSOP, TSSOP, PDIP type. The absolute maximum ratings table on this page lists the 9 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the 74HC4066 pinout, key specifications and maximum ratings, with the full datasheet PDF to preview below or download.
The 74HC4066; 74HCT4066 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.
