1. General description

The 74AHC1G66; 74AHCT1G66 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. The enable input is overvoltage tolerant. This feature allows the use of these devices as

translators in mixed voltage environments.
