Product details

Where it fits — industrial and general-purpose logic

Sourcing and lifecycle — still a current part

ROHS3 compliant, no lead or cadmium. For volume pricing and lead time, submit an RFQ through the usual independent distribution channel; availability is confirmed at quote time.

What the 2ns propagation delay means for your bus

At 2ns propagation delay, this latch adds almost no timing penalty on a bus. Compare that to a through-hole 74FCT573 (8.5ns) — the LVC part is over four times faster, which matters if you're latching addresses or data on a fast microcontroller or DSP memory interface.

Frequently asked questions

Is SN74LVC573APWR available in tape and reel or cut tape?

Yes, it is offered in both Tape & Reel (TR) and Cut Tape (CT) options.

Does SN74LVC573APWR have tri-state outputs?

Yes, the outputs are tri-state, controlled by the output-enable (OE) pin.

Is SN74LVC573APWR obsolete?

No, it is listed as Active in production with no end-of-life notice.
