DESCRIPTION
The 74LVX273 is a low voltage CMOS OCTAL
D-TYPE FLIP-FLOP WITH CLEAR fabricated with
sub-micron silicon gate and double-layer metal
wiring C2MOS technology. It is ideal for low
power, battery operated and low noise 3.3V
applications.

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. 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.
