CD54HC273 - High Speed CMOS Logic Octal D-Type Flip-Flops with Reset

The ’HC273 and ’HCT273 high speed octal D-Type flip-flops with a direct clear input are manufactured with silicon-gate CMOS technology. They possess the low power consumption of standard CMOS integrated circuits.

Information at the D inputis transferred to the Q outputs 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. All eight Q outputs are reset to a logic 0.
