It operates from a 4.5V to 5.5V supply — a straight 5V logic part, not a mixed-voltage device. The 32mA source and 64mA sink drive per channel handles heavily loaded buses typical of memory arrays, backplane segments, or parallel I/O banks where fan-out matters. The single-element, 10-bit organization means one package replaces ten discrete bus-keep or line-driver channels. ## Industrial temperature range and package fit Rated for -40°C to 85°C ambient, this transceiver suits factory automation, outdoor telecom cabinets, and engine-bay-adjacent electronics where commercial-grade 0°C to 70°C parts would drift out of spec. The 24-SOIC wide-body package (7.50mm body width) is a standard footprint for 10-bit bus transceivers; the 0.295-inch pitch matches common SOIC-24 land patterns. The mounting is surface-mount only — no through-hole variant in this order code. ## Output drive and 3-state bus control The 3-state outputs let multiple transceivers share a common bus without contention — the output enable control puts the drivers into high-impedance when the bus is owned by another device. The asymmetric drive (32mA high, 64mA low) is typical for ABT logic: the stronger low-side handles the higher capacitive load of a discharged bus line, while the high-side is sized for standard TTL thresholds. For a 10-bit bus running at 5V, this drive strength translates to clean edges on a 50pF–100pF load per line at moderate clock rates (50–100 MHz range, depending on trace length). ## Lifecycle and compliance TI lists the SN74ABT861DW as Active with no end-of-life notice. It is ROHS3 compliant, which covers the current EU RoHS exemption list. No LTB window or successor part has been published, so this remains a standard catalog item for new designs requiring a 5V 10-bit transceiver.","metaTitle":"SN74ABT861DW 74ABT 10-bit Transceiver, 32mA/64mA, 24-SOIC","metaDescription":"SN74ABT861DW from TI: 10-bit non-inverting transceiver, 3-state outputs, 4.5-5.5V supply, 32mA/64mA drive.

The 2245 has the same 32mA/64mA drive and 4.5V–5.5V supply range. If your design needs exactly 10 bits, the 861 is the correct part; for 8-bit buses the 2245 is a drop-in alternative in the same package."},{"question":"Can SN74ABT861DW be used as a level shifter between 5V and 3.3V logic?","answer":"No. The SN74ABT861DW is a 5V-only device with a supply range of 4.5V to 5.5V. Its input thresholds are TTL-compatible, but the outputs swing rail-to-rail at the 5V supply level. Driving a 3.3V input with a 5V output exceeds the absolute maximum ratings of most 3.3V CMOS inputs. For 5V-to-3.3V translation, look at the 74LVTH series (e.g., SN74LVTH16245A) which operates at 2.7V–3.6V and features 5V-tolerant inputs."},{"question":"Is SN74ABT861DW RoHS compliant?","answer":"Yes, the SN74ABT861DW is rated ROHS3 Compliant, meeting the latest EU RoHS exemption criteria including lead-free soldering requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74ABT861DW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74ABT861DW when reusing this data.
