DESCRIPTION
The 74LV74 is a low-voltage Si-gate CMOS device and is pin and
function compatible with 74HC/HCT74.
The 74LV74 is a dual positive edge triggered, D-type flip-flop with
individual data (D) inputs, clock (CP) inputs, set (S
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.
