Each of the two elements drives up to 24 mA per pin, enough to fan out to a dozen CMOS loads or a few TTL inputs without an external line driver. The 20-SOIC (5.30 mm wide) footprint matches the common SO-20 land pattern, so a board already using a 74AC244 in a wider package can swap to this narrower body without a layout change. ## Supply range — why 2V to 6V matters for the BOM The 2V to 6V supply range covers 3.3 V and 5 V logic rails without a level translator. In a mixed-voltage design — say a 3.3 V MCU talking to a 5 V peripheral — this buffer sits on the 3.3 V rail and still accepts 5 V-tolerant inputs because the 74AC inputs are over-voltage tolerant up to the supply limit. That saves a dedicated translator IC and the board space it would take. ## 24 mA output drive — what it means for fan-out Each output can source or sink 24 mA, which is enough to drive a small relay coil through a resistor, light a standard LED with a series resistor, or feed the clock input of several daisy-chained flip-flops. For a bus with more than ten loads, the cumulative capacitive load may still need a stronger driver, but for typical board-level buffering this is the sweet spot between drive strength and package thermal limits. ## Temperature grade and environment Rated for -40°C to 85°C ambient, the SN74AC244NSR is suited for industrial control cabinets, outdoor telecom enclosures, and factory-floor automation where the board sees temperature swings but not the extended automotive range. The 20-SOIC package is surface-mount, so it flows through a standard reflow profile with no special handling beyond MSL precautions. ## Lifecycle and sourcing posture Texas Instruments lists the SN74AC244NSR as Active on its product status, ROHS3 compliant. No last-time-buy notice or end-of-life window has been published. For a BOM line that needs a reliable 74AC244 buffer, this part is a low-risk choice for both new builds and production replenishment.","metaTitle":"SN74AC244NSR 74AC Buffer, Non-Inverting, 2V–6V, 20-SOIC","metaDescription":"TI SN74AC244NSR 74AC buffer with 3-state outputs, 24 mA drive, 2V–6V supply.
