Description

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.
