MM54C74 MM74C74 Dual D Flip-Flop
General Description
The MM54C74 MM74C74 dual D flip-flop is a monolithic
complementary 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
