open-in-new Find other D-type flip-flop

Description

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.
