MM54C174 MM74C174 Hex D Flip-Flop
General Description
The MM54C174 MM74C174 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
input All inputs are protected by diodes to V
