DESCRIPTION

The 74VHC273 is an advanced high-speed

CMOS OCTAL

D-TYPE FLIP FLOP WITH

CLEAR fabricated with sub-micron silicon gate

and

double-layer

metal

wiring

C

technology.

Information signals applied to D inputs are

transfered 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.

All inputs

and

outputs are

equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
