74VHCT573A

The 74VHCT573A is an advanced high-speed CMOS OCTAL D-TYPE LATCH with 3 STATE OUTPUT NON INVERTING fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.

This 8 bit D-Type latch is controlled by a latch enable input (LE) and an output enable input (OE ).

While the LE input is held at a high level, the Q outputs will follow the data inputs precisely.

When the LE is taken low, the Q outputs will be latched precisely at the logic level of D input data.

While the (OE ) input of the 74VHCT573A is low, the 8 outputs will be in a normal logic state (high or low logic level) and while high level the outputs will be in a high impedance state.

Power down protection of the 74VHCT573A 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.

All inputs and outputs of the 74VHCT573A are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
