Product data sheet
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.
2. Features and benefits
