The supplier device package is 20-TSSOP — no exposed pad, no thermal via needed.","metaTitle":"SN74ABT2244APWR Buffer, Non-Inverting, 3-State, 20-TSSOP, 5V","metaDescription":"Texas Instruments SN74ABT2244APWR dual 4-bit buffer with 3-state outputs. 4.5V–5.5V supply, 32mA/12mA drive, -40°C to 85°C.

The APWR suffix indicates the 20-TSSOP tape-and-reel variant. Functionally identical, but the footprint is different — check your board layout before substituting."},{"question":"What is the equivalent of SN74ABT2244APWR?","answer":"The closest functional equivalent is the SN74ABT2245DW, which is an 8-bit transceiver rather than a buffer. Both are 5 V, 3-state, 74ABT family parts. The 2244 is a buffer (data flows one direction); the 2245 is a transceiver (bidirectional with direction control). If your design needs bidirectional bus handling, the 2245 is the swap."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74ABT2244APWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74ABT2244APWR when reusing this data.
