FEATURES
DESCRIPTION
The 74AHC/AHCT14 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/AHCT14 provide six
inverting buffers with Schmitt-trigger
action. They are capable of
transforming slowly changing input
signals into sharply defined, jitter-free
output signals.
