TECHNICAL DATA
IN74LV74
Dual D-type flip-flop with set and reset;
positive-edge trigger
The IN74LV74 is a low-voltage Si-gate CMOS device and is pin and
function compatible with 74HC/HCT74.
The IN74LV74 is a dual positive edge triggered, D-type flip-flop with
individual data (D) inputs, clock (CP) inputs, set (S
D
) and (R
D
) 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.

*Both outputs will remain high as long as Set and
