74HCT4066 Datasheet PDF - NXP

●General description

●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 isturned off. Inputs include clamp diodes. This

●enables the use of current limiting resistors tointerface inputs to voltages in excess of

●VCC.
