Data sheet acquired from Harris Semiconductor SCHS174 CD74HC273, CD74HCT273 High Speed CMOS Logic Octal D-Type Flip-Flop with Reset Description The Harris CD74HC273 and CD74HCT273 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 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. All eight Q outputs are reset to a logic 0.
