If your board has a 2.5 V or 3.0 V rail, it works there too — no extra level shifter needed for the buffer itself. ## 24 mA drive — enough for most on-board buses Each output can sink or source 24 mA. That is plenty for driving a handful of CMOS inputs or a short ribbon cable inside the chassis. If you are driving a long backplane or a high-capacitance trace, you will want a bus transceiver with higher drive (like the 32 mA parts in the 74LVTH family). ## Two elements, four bits each — 8-bit bus buffer The part contains two independent buffer elements, each handling four bits. That gives you an 8-bit buffer in one 20-pin TSSOP package. The 3-state outputs let you share the bus with other devices — just pull the output-enable pins low to activate. ## Industrial temperature range — fine for most environments Rated from -40°C to 85°C ambient, this part suits factory automation, outdoor telecom cabinets, and indoor industrial controls. It is not qualified for automotive under-hood use (that would need AEC-Q100 and a wider temperature range like -40°C to 125°C). ## 20-TSSOP package — small footprint, standard pitch The 20-TSSOP body is 4.40 mm wide with a 0.65 mm lead pitch — a common, easy-to-rout package. Surface-mount only; no through-hole option. The narrow body saves board space compared to a 20-SOIC.","metaTitle":"SN74ALVCH244PWR Buffer, Non-Inverting, 1.65V-3.6V, 20-TSSOP","metaDescription":"TI SN74ALVCH244PWR buffer IC, 24mA output drive, 1.65V-3.6V supply, -40°C to 85°C, 20-TSSOP.","metaKeywords":null},"attributes":{"series":"74ALVCH","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"74ALVCH","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"1.65V ~ 3.6V","Number of Elements":"2","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"20-TSSOP","Current - Output High, Low":"24mA, 24mA","Number of Bits per Element":"4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.77","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.77000","currency":"USD"},{"qty":10,"price":"$0.67900","currency":"USD"},{"qty":25,"price":"$0.63760","currency":"USD"},{"qty":100,"price":"$0.52030","currency":"USD"},{"qty":250,"price":"$0.48324","currency":"USD"},{"qty":500,"price":"$0.41128","currency":"USD"},{"qty":1000,"price":"$0.32902","currency":"USD"},{"qty":2000,"price":"$0.29818","currency":"USD"},{"qty":6000,"price":"$0.29100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/be8190ab7ed56715c46b564f7d9f0597.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SN74ALVCH244PWR obsolete?","answer":"No — the SN74ALVCH244PWR is listed as an active product by Texas Instruments.
