The 3-state outputs let you disconnect the buffer from a shared data bus when the output-enable pins are deasserted, which is the standard arrangement for memory-address or peripheral-data buses on a 5V backplane. ## Industrial temperature range and the 20-SOIC wide-body footprint The package is a 20-SOIC with a 7.50mm body width, the wide-body variant. If your existing PCB layout uses the narrower 3.9mm SOIC footprint, this part will not fit without a board respin. The wide body also means the pin pitch is the standard 1.27mm, but the extra width gives better creepage distance for high-voltage adjacent traces on the same board. The 74ABT series has been in production for decades, and TI continues to support it for industrial and telecom customers who have not migrated to lower-voltage logic families. For a buyer filling a BOM line, the key fit criteria are the 5V-only supply rail, the 20-SOIC wide-body footprint, and the industrial temperature grade. If your design already uses a 3.3V or mixed-voltage bus, this buffer will not work without a level translator. The 32mA/12mA asymmetric drive is typical for 5V TTL-compatible bus buffering — adequate for driving a few CMOS loads or a short backplane trace, but not sized for high-capacitance cables.","metaTitle":"SN74ABT2244ADW Buffer, Non-Inverting, 20-SOIC, 5V Supply","metaDescription":"TI SN74ABT2244ADW dual 4-bit buffer with 3-state outputs, 32mA/12mA drive, -40°C to 85°C, 20-SOIC wide.

The 2244 is a buffer with separate input and output pins; the 2245 combines them with a direction-control pin. If your design needs bidirectional bus handling, the 2245 is the functional fork. For a unidirectional buffer, the 2244 is the correct choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74ABT2244ADW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74ABT2244ADW when reusing this data.
