Product details

Octal transparent latch for low-voltage buses

The Texas Instruments SN74LV573APWT is an octal D-type transparent latch with tri-state outputs, part of the 74LV low-voltage CMOS logic family. It holds eight bits of data when the latch-enable (LE) input is low, and passes input to output when LE is high. The tri-state outputs allow direct connection to a shared data bus — outputs go high-impedance when the output-enable (OE) input is high. This part is used in microcontroller and DSP systems for address/data latching, register storage, and bus buffering in industrial control, telecom, and general-purpose digital boards.

The 1 ns propagation delay leaves timing margin for fast buses.

The part is ROHS3 compliant.

Frequently asked questions

Is SN74LV573APWT directly equivalent to SN74LV573APW?

The SN74LV573APW is the same device in a different packaging option (tube vs tape & reel). The APWT suffix indicates Tape & Reel packaging. Functionally and electrically they are identical.
