TEXAS INSTRUMENTS CD54AC273 CD74AC273 CD54ACT273 CD74ACT273 Octal D Flip-Flop with Reset handbook

CD54AC273 / CD74AC273 are high performance CMOS logic D-type flip-flops with reset. 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.
