That 4.6 ns sets the timing margin for the latch-enable-to-output-valid window — at a 50 MHz bus cycle (20 ns period), the latch consumes under a quarter of the cycle, leaving headroom for the upstream address decode and downstream setup time. Output drive is rated 32 mA source, 64 mA sink — the asymmetric ratio is typical of BiCMOS outputs, where the sink side handles the heavier capacitive load of a shared bus backplane. The 64 mA sink allows direct driving of 50 pF traces without an external buffer, provided the total bus capacitance stays under the 50 pF derating curve. ## Supply and temperature — 5 V ±10 % rail, -40 to 85 °C ambient Packaged in a 20-TSSOP (4.40 mm width), the 0.65 mm pin pitch requires a standard 4-layer PCB for fan-out of the inner pins. The tape-and-reel format is the production-volume variant — the cut-tape option suits prototype runs of 10–50 pieces without reel fees.","metaTitle":"SN74ABT373PWR D-Type Transparent Latch, 4.6ns, 20-TSSOP","metaDescription":"Texas Instruments SN74ABT373PWR D-Type Transparent Latch, 8:8 circuit, 4.6ns propagation delay, 32/64mA output drive, industrial temp -40 to 85°C, 20-TSSOP.","metaKeywords":null},"attributes":{"series":"74ABT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Interface & Transceivers"],"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-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Independent Circuits":"1","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"20-TSSOP","Delay Time - Propagation":"4.6ns","Current - Output High, Low":"32mA, 64mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.84","priceTiers":[{"qty":1,"price":"$0.84000","currency":"USD"},{"qty":10,"price":"$0.75100","currency":"USD"},{"qty":25,"price":"$0.71280","currency":"USD"},{"qty":100,"price":"$0.58540","currency":"USD"},{"qty":250,"price":"$0.54720","currency":"USD"},{"qty":500,"price":"$0.48358","currency":"USD"},{"qty":1000,"price":"$0.38178","currency":"USD"},{"qty":2000,"price":"$0.35633","currency":"USD"},{"qty":6000,"price":"$0.33851","currency":"USD"},{"qty":10000,"price":"$0.32579","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7c9c5f9e022369f3423cdb85354b61d9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74ABT373PWR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source to SN74ABT373PWR?","answer":"The 74FCT573APC from the 74FCT family is a functional equivalent — same 8-bit D-type transparent latch with tri-state outputs.
