DESCRIPTION

The 74AC273 is an advanced high-speed CMOS

OCTAL D-TYPE FLIP FLOP WITH CLEAR

fabricated with sub-micron silicon gate and

Information signals applied to D inputs are

transfered to the Q output on the positive going

edge of the clock pulse.

When the CLEAR input is held low, the Q outputs

are held low independentely of the other inputs.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
