DESCRIPTION

The ACT273 is a high-speed CMOS OCTAL

D-TYPE FLIP FLOP WITH

CLEAR fabricated

with sub-micron silicon gate and double-layer

metal wiring C

power

applications

mantaining

high

speed

operation similar to equivalent Bipolar Schottky

TTL.

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 .

The device is designed to interface directly High

Speed CMOS systems with TTL, NMOS and

CMOS output voltage levels.

All inputs

and

outputs are

equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
