PIN ASSIGNMENT
The
KK
74LV74 is a low-voltage Si-gate CMOS device and is pin
and function compatible with 74HC/HCT74.
The
KK
74LV74 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.
Output voltage levels are compatible with input levels of CMOS,
NMOS and TTL IC

*Both outputs will remain high as long as Set and
Reset are low, but the output states are unpredictable
if Set and Reset go high simultaneously.
