General description
The 74AHC74; 74AHCT74 is a high-speed Si-gate CMOS device and is pin compatible
with Low-Power Schottky TTL (LSTTL). It is specied in compliance with JEDEC standard
No. 7-A.
The 74AHC74; 74AHCT74 is a dual positive-edge triggered, D-type ip-op with individual
data inputs (D), clock inputs (CP), set inputs (SD) and reset inputs (RD). It also has
complementary outputs (Q and Q).
The set and reset are asynchronous active LOW inputs that operate independent of the
clock input. Information on the data input is transferred to the Q output on the LOW to
HIGH transition of the clock pulse. The data inputs must be stable one set-up time prior to
the LOW to HIGH clock transition for predictable operation.
Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock
rise and fall times.
