topGeneral description
The 74HC/HCT74 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 74HC/HCT74 are dual positive-edge triggered, D-type flip-flops with individual data (D) inputs, clock (CP)
inputs, set (SD ) and reset (RD) inputs; also complementary Q and Q outputs.
The set and reset are asynchronous active LOW inputs and operate independently 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 D 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.
