DESCRIPTION

The AC174 is an high-speed CMOS HEX

D-TYPE FLIP FLOP WITH CLEAR fabricated

with sub-micron silicon gate and double-layer

metal wiring C

2MOS technology. It is ideal for low

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 .

All

inputs and

outputs

are

equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
