Supplier device package is 20-PDIP — the same body as the generic 20-DIP but with TI's specific mold compound and leadframe. For a legacy design that already has a 20-pin DIP footprint, this drops in without a layout change. Operating temperature range -40°C to 125°C (TA) qualifies this buffer for environments where the ambient inside the enclosure reaches 85°C or higher — industrial motor drives, outdoor telecom cabinets, and under-hood automotive modules that see engine-bay heat soak. For a non-safety-critical automotive module, the temperature margin alone may be sufficient; for safety-critical or PPAP-required lines, request the AEC-grade variant. ## 3-state bus architecture — shared data lines without contention The 3-state output type lets the buffer disconnect its outputs from the bus when the output-enable pin is inactive. This is the standard architecture for shared data buses (address/data lines in a microprocessor system, or a parallel sensor bus) where multiple devices drive the same traces. Non-inverting logic type (Buffer, Non-Inverting) means the output polarity matches the input — no inversion to account for in the signal path. Two elements of four bits each (Number of Elements: 2, Number of Bits per Element: 4) gives eight total channels, which maps directly to an 8-bit data bus or two 4-bit nibble buses. ## Sourcing posture — active, quoted to order ROHS3 compliant — no exemption issues for EU RoHS or California Proposition 65. The compliance documentation (RoHS certificate of compliance, REACH declaration) is available from Texas Instruments' compliance portal.","metaTitle":"SN74LVC244AN TI Buffer, 3-State, 20-DIP, 1.65-3.6V","metaDescription":"Texas Instruments SN74LVC244AN octal buffer, non-inverting, 3-state outputs. 1.65V-3.6V supply, 24mA drive, -40°C to +125°C.
