The 32 mA source / 64 mA sink current rating is the headline selection parameter. On a 5 V backplane with multiple loads, the 64 mA sink handles the low-level current from a dozen TTL inputs or a long trace's capacitive discharge. If your system is mixed-voltage, you need a level-translating buffer like the 74LVTH series.","metaTitle":"SN74ABT240ANSR Texas Instruments Buffer Inverting, 32/64mA","metaDescription":"Texas Instruments SN74ABT240ANSR 74ABT inverting buffer with 3-state outputs, 4.5V-5.5V supply, 32mA/64mA drive, -40°C to 85°C, 20-SOIC.","metaKeywords":null},"attributes":{"series":"74ABT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"74ABT","Package":"Tape & Reel (TR); Cut Tape (CT)","Logic Type":"Buffer, Inverting","Output Type":"3-State","Mounting Type":"Surface Mount","Package / Case":"20-SOIC (0.209\\\", 5.30mm 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-SO","Current - Output High, Low":"32mA, 64mA","Number of Bits per Element":"4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.16","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.16000","currency":"USD"},{"qty":10,"price":"$1.03800","currency":"USD"},{"qty":25,"price":"$0.98520","currency":"USD"},{"qty":100,"price":"$0.80940","currency":"USD"},{"qty":250,"price":"$0.75664","currency":"USD"},{"qty":500,"price":"$0.66864","currency":"USD"},{"qty":1000,"price":"$0.52788","currency":"USD"},{"qty":2000,"price":"$0.49800","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3feef1de7b4c5bc5114cb9ea3cca61de.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is SN74ABT240ANSR RoHS compliant?","answer":"Yes, it is ROHS3 compliant, meeting the current EU RoHS directive without exemptions."},{"question":"Can SN74ABT240ANSR be used as a replacement for SN74ABT240ADW?","answer":"The SN74ABT240ADW is the same die in a different package (SOIC wide-body versus the narrow 20-SO of the ANSR suffix).
