74VHCT273A Octal D Type Flip Flop with Clear

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.
