1. General description

The 74HC1G66; 74HCT1G66 is a single-pole, single-throw analog switch with two input/output

terminals (nY and nZ) and a digital 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.

The HCT device features control inputs with reduced input threshold levels to allow interfacing to

TTL logic levels.
