1. General description
The 74AHC08; 74AHCT08 are quad 2-input AND gates. Inputs are overvoltage tolerant. This
feature allows the use of these devices as translators in mixed voltage environments.
2. Features and benefits
Wide supply voltage range from 2.0 V to 5.5 V
Input levels:
For 74AHC08: CMOS level
For 74AHCT08: TTL level
Balanced propagation delays
All inputs have a Schmitt-trigger action
Overvoltage tolerant inputs to 5.5 V
High noise immunity
CMOS low power dissipation
ESD protection:
HBM EIA/JESD22-A114E exceeds 2000 V
MM EIA/JESD22-A115-A exceeds 200 V
CDM EIA/JESD22-C101C exceeds 1000 V
Latch-up performance exceeds 100 mA per JESD 78 Class II Level A
Multiple package options
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
