DESCRIPTION

The LVQ174 is a low voltage CMOS HEX
D-TYPE FLIP FLOP WITH CLEAR NON
INVERTING fabricated with sub-micron silicon
gate and double-layer metal wiring C
technology.It is idealfor low power and low noise

3.3Vapplications.
Information signals applied to D inputs are

transfered to the Q outputs on the positive going
edgeof the clock pulse.

Whenthe CLEAR input is held low, the Q outputs
are held low independentelyof the other inputs .

It has better speed performance at 3.3V than 5V
LS-TTL family combined with the true CMOS low
powerconsumption.

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