Dual D-type flip-flop with set and reset;
positive-edge trigger

The KK74LV74 is a low-voltage Si-gate CMOS device and is pin and function compatible with 74HC/HCT74.
The KK74LV74 is a dual positive edge triggered, D-type flip-flop with individual data (D) inputs, clock (CP) inputs, set (SD) and (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.
