The 35ns propagation delay is moderate for 5V HCT. Output drive is 6mA source and 6mA sink. ## Lifecycle and sourcing reality The CD74HCT373M carries an Active lifecycle status and is ROHS3 compliant. For a BOM line that needs a 5V transparent latch in SOIC-20, this is a straightforward, low-risk procurement. ## 35ns propagation delay — what it means for the bus The 35ns propagation delay is the time from the latch-enable or data input edge to a valid output, measured at the rated supply and load. In a typical address-latching application, this delay eats into the memory access window: if the CPU drives the address bus and asserts LE, the latch outputs settle 35ns later. That leaves the remaining cycle time for the memory device to respond. For a 50ns SRAM on a 100ns bus cycle, the margin is tight but workable. For faster processors or pipelined buses, a faster latch family (like 74FCT with 8.5ns delay) would be needed — but that comes with a narrower temperature range.","metaTitle":"CD74HCT373M 74HCT D-Type Transparent Latch, 35ns","metaDescription":"CD74HCT373M 74HCT octal D-type transparent latch with tri-state outputs. 4.5V–5.5V supply, 35ns propagation delay, -55°C to 125°C range.","metaKeywords":null},"attributes":{"series":"74HCT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"74HCT","Circuit":"8:8","Package":"Tube","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":"-55°C ~ 125°C","Supplier Device Package":"20-SOIC","Delay Time - Propagation":"35ns","Current - Output High, Low":"6mA, 6mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.53","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.53000","currency":"USD"},{"qty":10,"price":"$1.36300","currency":"USD"},{"qty":25,"price":"$1.29400","currency":"USD"},{"qty":100,"price":"$1.06300","currency":"USD"},{"qty":250,"price":"$0.99364","currency":"USD"},{"qty":500,"price":"$0.87810","currency":"USD"},{"qty":1000,"price":"$0.69324","currency":"USD"},{"qty":2500,"price":"$0.65400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/96c3422e761fda4d456c47d89a584b4a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between CD74HCT373M and 74FCT573APC?","answer":"The 74FCT573APC is a faster latch (8.5ns propagation delay vs 35ns) but is rated only for 0°C to 70°C commercial temperature range, versus the -55°C to 125°C military range of the CD74HCT373M. The 74FCT573APC also comes in a through-hole package (Bulk) and operates at 4.75V supply.

Typical applications include microcontroller memory interfacing, FPGA configuration latching, and general-purpose parallel I/O expansion.
