1. 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 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 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.
