In a backplane or memory-interface latch, 1 ns adds negligible skew to the bus timing budget — the designer can treat it as near-zero for clock rates up to several hundred megahertz. Combined with 24 mA symmetric output drive, the latch can drive moderate capacitive loads on a short PCB trace without needing a separate buffer. ## Industrial temperature grade and package Rated for -40°C to 85°C, this part suits outdoor telecom cabinets, factory-floor PLCs, and motor-drive control logic where ambient temperature swings are routine. The 20-TSSOP package saves board area compared to wide-body SOIC — about 4.4 mm body width — and the surface-mount footprint matches standard pick-and-place assembly.","metaTitle":"SN74ALVCH373PWR D-Type Transparent Latch, 1ns delay","metaDescription":"TI SN74ALVCH373PWR octal D-type transparent latch with tri-state output, 1.65V-3.6V supply, 1ns propagation delay, 24mA drive, -40°C to 85°C, 20-TSSOP, ROHS3","metaKeywords":null},"attributes":{"series":"74ALVCH","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"74ALVCH","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":"1.65V ~ 3.6V","Independent Circuits":"1","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"20-TSSOP","Delay Time - Propagation":"1ns","Current - Output High, Low":"24mA, 24mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.87","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.87000","currency":"USD"},{"qty":10,"price":"$0.78200","currency":"USD"},{"qty":25,"price":"$0.74200","currency":"USD"},{"qty":100,"price":"$0.60950","currency":"USD"},{"qty":250,"price":"$0.56976","currency":"USD"},{"qty":500,"price":"$0.50350","currency":"USD"},{"qty":1000,"price":"$0.39750","currency":"USD"},{"qty":2000,"price":"$0.37500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/61aa2dbe089a9532ff2418fb7ac7ad14.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SN74ALVCH373PWR RoHS compliant?","answer":"Yes, the SN74ALVCH373PWR is ROHS3 compliant."},{"question":"Can SN74ALVCH373PWR be used in 3.3V systems?","answer":"Yes, its supply voltage range of 1.65 V to 3.6 V includes 3.3 V directly, with no level-shifter needed."},{"question":"Is SN74ALVCH373PWR a direct replacement for SN74ALVCH373DWR?","answer":"The SN74ALVCH373PWR and SN74ALVCH373DWR share the same logic function (octal D-type transparent latch with tri-state outputs) and supply range; the difference is the package — the PWR suffix indicates a 20-TSSOP body, while the DWR suffix indicates a 20-SOIC wide body.
