DESCRIPTION

The 74LVQ273 is a low voltage CMOS OCTAL

D-TYPE FLIP FLOP WITH CLEAR fabricated with

sub-micron silicon gate and double-layer metal

and low noise 3.3V applications.

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.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
