1. General description

The 74AHC00; 74AHCT00 are quad 2-input NAND gates. Inputs are overvoltage tolerant. This

feature allows the use of these devices as translators in mixed voltage environments.

2. Features

? Wide supply voltage range from 2.0 V to 5.5 V

? Input levels:

? For 74AHC00: CMOS level

? For 74AHCT00: TTL level

? Balanced propagation delays

? All inputs have Schmitt-trigger actions

? Overvoltage tolerant inputs to 5.5 V
