It holds bus data while the latch-enable (LE) is low; when LE is high, the outputs follow the inputs transparently. The output-enable (OE) bar puts all eight outputs into high-impedance when driven high, allowing multiple devices to share the same bus without contention. ## Industrial temperature range Rated for -40°C to 85°C, the SN74ABT573ADWR suits factory-floor automation, outdoor telecom cabinets, and motor-drive control boards where the ambient can swing well beyond office-grade conditions. ## Active lifecycle — no LTB pressure TI lists this part as Active and ROHS3 compliant. There is no last-time-buy notice or obsolescence risk on the horizon. It remains a valid choice for both new designs and sustaining production.","metaTitle":"SN74ABT573ADWR D-Type Transparent Latch","metaDescription":"TI SN74ABT573ADWR octal D-type transparent latch with tri-state outputs. 4ns propagation delay, 32/64mA drive, -40 to 85°C, 20-SOIC.","metaKeywords":null},"attributes":{"series":"74ABT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Series":"74ABT","Circuit":"8:8","Package":"Tape & Reel (TR); Cut Tape (CT)","Logic Type":"D-Type Transparent Latch","Output Type":"Tri-State","Mounting Type":"Surface Mount","Package / Case":"20-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Independent Circuits":"1","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"20-SOIC","Delay Time - Propagation":"4ns","Current - Output High, Low":"32mA, 64mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.11","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.11000","currency":"USD"},{"qty":10,"price":"$0.99400","currency":"USD"},{"qty":25,"price":"$0.94400","currency":"USD"},{"qty":100,"price":"$0.77530","currency":"USD"},{"qty":250,"price":"$0.72472","currency":"USD"},{"qty":500,"price":"$0.64046","currency":"USD"},{"qty":1000,"price":"$0.50562","currency":"USD"},{"qty":2000,"price":"$0.47700","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2c0ab4e19c57db68be3fa6d46cf58791.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74ABT573ADWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74ABT573ADWR when reusing this data.
