It holds eight bits of data when the latch-enable signal goes low, and the tri-state outputs let multiple devices share a common bus without contention. Typical applications include address/data latching in microprocessor systems, bus isolation buffers, and register storage in 5V logic boards — think office equipment, telecom line cards, and benchtop instrumentation where the 0°C to 70°C commercial temperature range fits. ## Lifecycle and sourcing SN74ALS373ADWR is listed as Active with ROHS3 compliance. No imminent end-of-life notice on this line. For dual-sourcing considerations, the 74FCT573APC from the 74FCT series offers a functionally similar D-type transparent latch but in a through-hole package and with an 8.5ns propagation delay; the pinout is not guaranteed compatible, so verify the footprint before substituting.","metaTitle":"SN74ALS373ADWR D-Type Transparent Latch, 6ns, 20-SOIC","metaDescription":"TI SN74ALS373ADWR octal D-type transparent latch with tri-state outputs. 4.5V-5.5V supply, 6ns propagation delay, 20-SOIC.

SN74ALS373ADW ships in tubes; SN74ALS373ADWR ships in tape and reel. The die, electrical specs, and 20-SOIC package are identical. Choose the 'R' suffix for automated assembly lines, the non-R for hand-assembly or low-volume builds."},{"question":"What is the propagation delay of SN74ALS373ADWR?","answer":"The propagation delay is 6ns from input to output under standard test conditions. This is fast enough for most 5V microprocessor buses but slower than 74FCT or 74AC series equivalents."},{"question":"What is the closest functional second-source for SN74ALS373ADWR?","answer":"The 74FCT573APC is a functionally similar D-type transparent latch from the 74FCT series, but it comes in a through-hole package and has an 8.5ns propagation delay.
