DESCRIPTION
The 74AC273 is an advanced high-speed CMOS
OCTAL D-TYPE FLIP FLOP WITH CLEAR
fabricated with sub-micron silicon gate and
double-layer metal wiring C
2
MOS technology.
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.
