OPERATING VOLTAGE RANGE:
(OPR) = 2V to 3.6V (1.2V Data Retention)
Information signals applied to D inputs are
transferred to the Q outputs on the positive going
edge of the clock pulse.
When the CLEAR input is held low, the Q outputs
are held low independently of the other inputs.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage.
This device can be used to interface 5V to 3V
system. It combines high speed performance with
the true CMOS low power consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.

DESCRIPTION
The 74LVX174 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 MOS
technology. It is ideal for low power, battery
operated and low noise 3.3V applications.
