MM74C74
Dual D-Type Flip-Flop
General Description
The MM74C74 dual D-type flip-flop is a monolithic comple-
mentary MOS (CMOS) integrated circuit constructed with
N- and P-channel enhancement transistors. Each flip-flop
has independent data, preset, clear and clock inputs and Q
and Q outputs. The logic level present at the data input is
transferred to the output during the positive going transition
of the clock pulse. Preset or clear is independent of the
clock and accomplished by a low level at the preset or clear
input.
