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
