Product details

Eight-bit transparent latch with tri-state bus control

The SN74HC573APWR is an octal D-type transparent latch from the 74HC series. It holds eight bits while latch-enable is high, and tri-state outputs allow bus sharing. Supply range is 2V to 6V.

Lifecycle and sourcing

The SN74HC573APWR carries an Active lifecycle status and is ROHS3 compliant. No end-of-life notice or last-time-buy window is in effect. No production-status uncertainty here; it's a standard catalog item suitable for both prototyping and production BOMs.

Frequently asked questions

What is the difference between SN74HC573APWR and SN74HC573AN?

The primary difference is the package: SN74HC573APWR is a surface-mount 20-TSSOP, while SN74HC573AN is a through-hole DIP package. Both share the same 74HC logic family, 2V–6V supply, 23ns propagation delay, and -40°C to 85°C temperature range. The choice depends on board assembly method.
