The 74AHC74; 74AHCT74 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. 7-A.

The 74AHC74; 74AHCT74 is a dual positive-edge triggered, D-type flip-flop with individual
data inputs (D), clock inputs (CP), set inputs (SD) and reset inputs (RD). It also has
complementary outputs (Q andQ).
