DESCRIPTION

The ACT174 is an high-speed CMOS HEX

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 eqivalent 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 independentelyof 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.
