What are the key features of the 74HC573?

It features a wide supply voltage range (2.0V to 6.0V), high noise immunity, and 3-state non-inverting outputs.

How does the latch enable (LE) input work?

When LE is HIGH, the latch is transparent. When LE is LOW, the latch stores the data present at the inputs during the preceding set-up time.

What is the purpose of the output enable (OE) input?

A HIGH on the OE input forces the outputs into a high-impedance OFF-state, allowing for bus-oriented applications.

What is the sourcing status of the 74HC573?

The part is currently active and widely available from major distributors.

What is the pinout of 74HC573D,653?

Use the 74HC573D,653 datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about 74HC573D,653 pinout to locate pins, power rails, and interface signals before layout.
