DESCRIPTION The M54HC273 is an high speed CMOS OCTAL D TYPE FLIP FLOP WITH CLEAR fabricated with silicon gate C2MOS technology.

Information signals applied to D inputs are transferred to the Q outputs on the positive-going edge of the clock pulse. When the CLEAR input is held low, the Q output are in the low logic level independent of the other inputs. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
