Description
The CD74AC175 and CD74ACT175 are quad D flip-flops
with reset that utilize the Harris Advanced CMOS Logic tech-
nology. Information at the D input is transferred to the Q and
Q outputs on the positive-going edge of the clock pulse. All
four flip-flops are controlled by a common clock (CP) and a
common reset (MR). Resetting is accomplished by a LOW
logic level independent of the clock.
