Two independent enable pins (one per 4-bit bank) give you granular control over the output banks, which is handy when you're gating separate bus segments from a single package. If your board runs 3.3 V logic, this part won't work — you'd need a 74LVC or 74AHCT variant instead. The 16 mA symmetric drive at both output high and low is enough to light a standard LED or drive a handful of CMOS inputs, but it's not a line driver. For heavier bus loads (32 mA or more), the SN74ABT2245DW transceiver is a closer functional match, though it's a single 8-bit device with a different pinout. ## Industrial temperature range and active production The lifecycle status is Active, so TI is still manufacturing it — no last-time-buy pressure, no obsolete-parts scramble. The 20-TSSOP package (4.40 mm wide) is a common footprint; the narrow body means you'll want a steady hand and good flux.","metaTitle":"SN74LV244ATPW 74LV Buffer, Non-Inverting, 3-State, 20-TSSOP","metaDescription":"Texas Instruments SN74LV244ATPW, 74LV series octal buffer with 3-state outputs, 16mA drive, 4.5V–5.5V supply, -40°C to 85°C, 20-TSSOP.","metaKeywords":null},"attributes":{"series":"74LV","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74LV","Package":"Tube","Logic Type":"Buffer, Non-Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Number of Elements":"2","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"20-TSSOP","Current - Output High, Low":"16mA, 16mA","Number of Bits per Element":"4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.34","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.34000","currency":"USD"},{"qty":10,"price":"$1.20100","currency":"USD"},{"qty":25,"price":"$1.13960","currency":"USD"},{"qty":100,"price":"$0.93620","currency":"USD"},{"qty":250,"price":"$0.87512","currency":"USD"},{"qty":500,"price":"$0.77338","currency":"USD"},{"qty":1000,"price":"$0.61056","currency":"USD"},{"qty":2500,"price":"$0.57600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/16af55a3ceb50649483975ef1a8acca4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can SN74LV244ATPW be used at 3.3V?","answer":"No. This buffer is designed for 5 V logic rails only.

The SN74ABT2245DW is a different function (transceiver vs buffer) and different pinout.
