• Buffered Inputs
The CD74AC174 and ’ACT174 are hex D flip-flops with reset
that utilize Advanced CMOS Logic technology. Information at
the D input is transferred to the Q output on the positive-
going edge of the clock pulse. All six flip-flops are controlled
by a common clock (CP) and a common reset (MR). Reset-
ting is accomplished by a low voltage level independent of
the clock.
