MM54C74MM74C74 Dual D Flip-Flop

General Description

The MM54C74MM74C74 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
