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.
1 ns propagation delay — timing margin for fast buses
The 1 ns propagation delay leaves timing margin for fast buses.
Industrial temperature range — -40°C to 85°C
Rated for -40°C to 85°C, this latch suits factory-floor automation and outdoor telecom cabinets. The 20-TSSOP package keeps the board footprint small.
Active lifecycle — no LTB risk
The SN74LV573APWT carries an Active lifecycle status. The part is ROHS3 compliant. For a BOM freeze or a long production run, this part does not carry a last-time-buy risk.
