OPERATING VOLTAGE RANGE:

(OPR) = 4.5V to 5.5V

When the (OE) input is low, the 8 outputs will be in

a normal logic state (high or low logic level) and

when (OE) is high, the outputs will be in a high

impedance state.

The Output control does not affect the internal

operation of flip flop; that is, the old data can be

retained or the new data can be entered even

while the outputs are off.

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.

DESCRIPTION

The 74VHCT574A is an advanced high-speed

CMOS OCTAL D-TYPE FLIP FLOP with 3 STATE

OUTPUTS NON INVERTING fabricated with

sub-micron silicon gate and double-layer metal

wiring C MOS technology.

These 8 bit D-Type flip-flop is controlled by a clock

input (CK) and an output enable input (OE).

On the positive transition of the clock, the Q

outputs will be set to the logic states that were

setup at the D inputs.
