Its supply range from 1.65V to 3.6V covers the common 1.8V, 2.5V, and 3.3V logic rails, making it a natural fit for bridging between voltage domains in mixed-signal systems. Each of the two elements handles four bits, giving you an octal buffer in one 20-TSSOP package. ## 24 mA symmetric drive — sizing the load budget Both the high-level and low-level output current are rated at 24 mA each, which is symmetric drive capability typical of ALVC-family buffers. For a 3.3V rail, that translates to driving a 140 Ω load to a valid logic level — enough for a single TTL/CMOS fan-out of ten or more standard loads. If your bus has a higher capacitive load or long trace length, budget derating: at 50 pF load and 3.3V, propagation delay stays under the family's typical sub-4 ns window, but a 100 pF trace adds roughly 1 ns of edge degradation. ## Industrial temperature range — deployment context Rated for -40°C to 85°C ambient, this part suits factory automation, outdoor telecom cabinets, and indoor industrial controls. It does not carry AEC-Q100 qualification, so it is not specified for under-hood automotive or engine-bay environments where the junction temperature would exceed 85°C consistently. For a 105°C or 125°C requirement, you would step to the 74LVC or 74AHC automotive-grade variants. ## Active lifecycle — no LTB risk on this BOM line ROHS3 compliant per the compliance listing. ## 20-TSSOP — footprint and board integration Housed in a 20-pin TSSOP with 0.65 mm pitch and 4.40 mm body width, the package is a surface-mount only form factor. The 0.173-inch (4.40 mm) width is standard for TSSOP-20, and the footprint matches the industry-common land pattern for this package family. No exposed thermal pad — all dissipation goes through the leads, so for continuous high-drive scenarios (all 8 outputs at 24 mA simultaneously), check the package thermal impedance against your ambient temperature and airflow.","metaTitle":"SN74ALVC244PW Buffer, Non-Inverting, 1.65V-3.6V, 20-TSSOP","metaDescription":"TI SN74ALVC244PW octal buffer with 3-state outputs, 24mA drive, 1.65V-3.6V supply, -40°C to 85°C.

With a supply voltage range of 1.65V to 3.6V, you can power the device at 2.5V and drive the inputs with 3.3V logic. The 3-state outputs will swing to the 2.5V rail, translating the signal. Verify that the 3.3V input levels exceed the VIH minimum at 2.5V supply (typically 1.75V for ALVC), which they will."},{"question":"Is SN74ALVC244PW 5V tolerant?","answer":"The datasheet specifies a maximum supply voltage of 3.6V, and the device is not rated for 5V-tolerant inputs. Applying 5V to any pin when the device is powered at 3.3V or lower may exceed absolute maximum ratings. For 5V-tolerant buffering, consider the 74LVC or 74AVC families."},{"question":"What is the difference between SN74ALVC244PW and SN74LVC244APW?","answer":"Both are octal non-inverting buffers in 20-TSSOP packages, but the 74LVC244A operates over a slightly wider supply range (1.65V to 3.6V same as ALVC) and typically offers 5V-tolerant inputs, which the ALVC244 does not. The LVC variant also has a different drive strength curve and propagation delay spec. For a direct pin-compatible replacement with 5V tolerance, the SN74LVC244APW is the closer match; the ALVC244 is better suited for low-voltage-only buses where 5V tolerance is not needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74ALVC244PW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74ALVC244PW when reusing this data.
