GeneralGeneralGeneralGeneral The 74HC273D is a high speed CMOS OCTAL D-TYPE FLIP FLOP fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. Information signals applied to D inputs are transferred to the Q outputs on the positive going edge of the clock pulse. When the CLR input is held, the Q outputs are at a low logic level independent of the other inputs. All inputs are equipped with protection circuits against static discharge or transient excess voltage. 3. 3. FeaturesFeatures 3. 3.
