DESCRIPTION

The 74VHCT273A is an advanced high-speed

CMOS OCTAL D-TYPE FLIP FLOP WITH CLEAR

fabricated

with

sub-micron silicon gate and

double-layer metal wiring C2MOS technology.

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 outputs 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 since all

inputs are equipped with TTL threshold.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
