The 3-state outputs let you connect it directly to a shared data bus — memory address lines, peripheral chip selects, or a microcontroller port — without external bus switches or extra logic. ## Output drive: 32 mA sourcing, 64 mA sinking The asymmetric drive — 32 mA per output when sourcing, 64 mA when sinking — is the spec that determines how many loads this buffer can drive and at what speed. The higher sink current is typical for TTL-compatible logic where the output pulls down against a pull-up or a terminated line. For a 3.3 V backplane or a memory bus with series termination, the 64 mA sink gives you clean low-level edges into a 50 Ω or 33 Ω load. The 32 mA source side still drives four to eight standard 74LVTH inputs without fan-out concerns. If your design needs symmetric drive or non-inverting logic, you would look at the 74LVTH162245 family instead. ## Temperature range and deployment It is not automotive-grade (no AEC-Q100), so skip it for under-hood or chassis-domain designs. For an unheated enclosure in a northern-climate factory, the -40°C cold start is fine; the 85°C top end covers most convection-cooled cabinets. If your board sits near a hot power stage or in a sealed enclosure, budget for the junction temperature rise from the 64 mA sink current.","metaTitle":"SN74LVTH240PW Buffer, Inverting 3-State 20-TSSOP, 32/64mA","metaDescription":"Texas Instruments SN74LVTH240PW dual 4-bit inverting buffer with 3-state outputs. 2.7V-3.6V supply, 32mA/64mA drive, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"74LVTH","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74LVTH","Package":"Tube","Logic Type":"Buffer, Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 3.6V","Number of Elements":"2","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"20-TSSOP","Current - Output High, Low":"32mA, 64mA","Number of Bits per Element":"4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.26","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.26000","currency":"USD"},{"qty":10,"price":"$1.12900","currency":"USD"},{"qty":25,"price":"$1.07160","currency":"USD"},{"qty":100,"price":"$0.88010","currency":"USD"},{"qty":250,"price":"$0.82272","currency":"USD"},{"qty":500,"price":"$0.72706","currency":"USD"},{"qty":1000,"price":"$0.57399","currency":"USD"},{"qty":2500,"price":"$0.54150","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f1cf559cdb6ea3141891d42d04f53b2a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output current for SN74LVTH240PW?","answer":"Each output can source 32 mA and sink 64 mA.
