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
edgeof theclockpulse.

Whenthe CLEARinput 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
CMOSoutput voltagelevels.

All inputs and outputs are equipped with
protectioncircuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
