Data sheet acquired from Harris Semiconductor SCHS249B CD54AC273, CD74AC273 CD54ACT273, CD74ACT273 Octal D Flip-Flop with Reset Description The ’AC273 and ’ACT273 devices are octal D-type ip-ops 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 ip-ops are controlled by a common clock (CP) and a common reset (MR). Resetting is accomplished by a low voltage level independent of the clock.
