MM74C174
Hex D-Type Flip-Flop
General Description
The MM74C174 hex D-type flip-flop is a monolithic comple-
mentary 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 inde-
pendent of clock and accomplished by a low level at the
clear input. All inputs are protected by diodes to V
CC
and
GND.
