It operates from a 4.5V to 5.5V supply, meaning it is a strict 5V logic device — do not feed it 3.3V rails without a level translator, as the input thresholds are not TTL-compatible at lower voltages. The output drive is asymmetric: 32 mA source, 64 mA sink. That 2:1 ratio is deliberate — it handles the higher current draw of terminated backplanes or capacitive loads on the falling edge without overshoot on the rising edge. For a typical automotive ECU bus running at 5V, this buffer can drive eight standard LSTTL loads per output with margin. ## Package and temperature grade for under-hood or cabin placement Housed in a 20-TSSOP (4.40 mm width, 0.65 mm pitch), the part fits the common SOIC-20 footprint variant. The -40°C to 85°C operating range covers cabin and under-hood environments where the ambient stays below the 85°C mark — not suitable for direct engine-bay exposure (125°C), but fine for body controllers, infotainment, or transmission control units with adequate airflow. The supplier device package is 20-TSSOP, identical to the package/case field — no hidden paddle or exposed pad to worry about. Standard reflow profile for TSSOP applies; MSL is not listed but 74ABT family devices typically ship at MSL 1 or 2. ## Active lifecycle — still a valid BOM line for new designs ROHS3 compliant, so no exemption sunset risk on the horizon. The part ships in Tape & Reel or Cut Tape options, matching standard pick-and-place workflows.","metaTitle":"SN74ABT541BIPWRQ1 Buffer, 8-bit, 3-State, 20-TSSOP, AEC-Q100","metaDescription":"TI SN74ABT541BIPWRQ1 automotive 8-bit non-inverting buffer, 4.5-5.5V supply, 32/64 mA drive, -40°C to 85°C, 20-TSSOP.
