1. 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 is turned off. Inputs include clamp diodes. This enables the use of current

limiting resistors to interface inputs to voltages in excess of VCC.

2. Features and benefits
