Each channel sinks 64mA and sources 32mA. ## Output drive and bus loading The 32mA source and 64mA sink per output are the headline numbers for bus design. On a 3.3V backplane with 50pF per load and a 10MHz clock, the 64mA sink handles the capacitive discharge without ringing—but check the simultaneous switching output limit in the datasheet if you're toggling all eight bits at once. For a memory-address bus driving four DRAM loads, this buffer clears the fan-out without needing a secondary buffer stage. ## Active lifecycle, no end-of-life risk The SN74LVTH540PW carries an Active product status with ROHS3 compliance. There is no last-time-buy notice, no NRND flag, and no successor part announced. For a BOM line that needs a stable 8-bit inverting buffer for the next several production years, this part is a safe call—no forced redesign cycle from a sudden EOL.","metaTitle":"SN74LVTH540PW Buffer Inverting 3-State, 20-TSSOP, 2.7V-3.6V","metaDescription":"SN74LVTH540PW 8-bit inverting buffer with 3-state outputs, 32mA/64mA drive, 2.7V-3.6V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"74LVTH","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"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":"1","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"20-TSSOP","Current - Output High, Low":"32mA, 64mA","Number of Bits per Element":"8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.21","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.21000","currency":"USD"},{"qty":10,"price":"$1.98900","currency":"USD"},{"qty":25,"price":"$1.87600","currency":"USD"},{"qty":100,"price":"$1.59850","currency":"USD"},{"qty":250,"price":"$1.50096","currency":"USD"},{"qty":500,"price":"$1.31334","currency":"USD"},{"qty":1000,"price":"$1.08820","currency":"USD"},{"qty":2500,"price":"$1.06200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2d3193f234b4a07263f61d67366987b1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SN74LVTH540PW compatible with 3.3V logic?","answer":"Yes, the SN74LVTH540PW operates from 2.7V to 3.6V supply, making it native 3.3V logic. Its LVTTL-compatible input thresholds (VIL 0.8V max, VIH 2.0V min) interface directly with 3.3V FPGAs, MCUs, and other 74LVTH or LVC devices."},{"question":"What is the difference between SN74LVTH540PW and SN74LVTH541PW?","answer":"The SN74LVTH540PW is an inverting buffer (output = inverted input), while the SN74LVTH541PW is a non-inverting buffer. Both are 8-bit, 3-state, same supply range and package. Choose the 540 for active-low bus signals or when you need an inversion in the data path; choose the 541 for a straight-through non-inverted path."},{"question":"What is the lead time for SN74LVTH540PW?","answer":"Lead time is confirmed at quote time through independent distribution.
