The 74AHC14; 74AHCT14 is a high-speed Si-gate CMOS device and is pin compatible
with Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard
No. 7A.
The 74AHC14; 74AHCT14 provides six inverting buffers with Schmitt-trigger action. They
are capable of transforming slowly changing input signals into sharply defined, jitter-free
output signals.
