Octal D Flip-Flop with Reset August 1998 -Revised July 2002 Features Description Buffered Inputs The ’AC273 and ’ACT273 devices are octal D-type 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 eight flip-flops
are controlled by a common clock (CP) and a common reset
(MR). Resetting is accomplished by a low voltage level
independent of the clock. Typical Propagation Delay
