FEATURES
DESCRIPTION
The 74AHC/AHCT02 are high-speed
Si-gate CMOS devices and are pin
compatible with low power Schottky
TTL (LSTTL). They are specified in
compliance with JEDEC standard
No. 7A.
The 74AHC/AHCT02 provides the
Quad 2-input OR function.

ESD protection:
HBM EIA/JESD22-A114-A
exceeds 2000 V
MM EIA/JESD22-A115-A
exceeds 200 V
CDM EIA/JESD22-C101

Balanced propagation delays
All inputs have Schmitt-trigger
actions
Inputs accepts voltages higher than
V
For AHC only:
operates with CMOS input levels
For AHCT only:
operates with TTL input levels
