MM54C174MM74C174 Hex D Flip-Flop

General Description

The MM54C174MM74C174 hex D flip-flop is a monolithic

complementary MOS (CMOS) integrated circuit constructed

with N- and P-channel enhancement transistors All have a

direct clear input Information at the D inputs meeting the

setup time requirements is transferred to the Q outputs on

the positive-going edge of the clock pulse Clear is indepen-

dent of clock and accomplished by a low level at the clear
