Beschreibung von CD54HC273
The CD54HC273, CD74HC273, CD54HCT273, and CD74HCT273 high speed octal D-Type flip-flops with a direct clear input are manufactured with silicongate CMOS technology. The devices possess the low power consumption of standard CMOS integrated circuits.
Information at the D input transfers to the Q outputs on the positive-going edge of the clock pulse. All eight flip-flops are controlled by a common clock (CLK) and a common reset (/CLR). Resetting is accomplished by a low voltage level independent of the clock. All eight Q outputs reset to a logic 0.
