DESCRIPTION

The M74HCT273 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.
