SN74LV8T541

SN74LV8T541 is the Texas Instruments octal buffer and line driver with 3-state outputs and integrated single-supply voltage translation, covered by datasheet SLVSJR1 (August 2025). One device bridges logic domains without a separate level shifter: it runs from 1.65 V to 5.5 V, accepts 5.5 V-tolerant inputs regardless of supply, supports up-translation such as 1.2 V to 1.8 V, 1.8 V to 3.3 V and 3.3 V to 5.0 V as well as down-translation, and passes data up to 150 Mbps at 5 V and 3.3 V supplies, with latch-up performance above 250 mA per JESD 78 Class II. For mixed-voltage boards this removes a BOM line and the associated layout and sourcing risk every time an MCU, sensor or legacy 5 V peripheral changes voltage domain. Selection advice: orderables are SN74LV8T541PWR (TSSOP-20), SN74LV8T541DGSR (VSSOP-20) and SN74LV8T541RKSR (VQFN-20), so quote the full code for the footprint needed; this is the industrial device, and automotive builds use the separate SN74LV8T541-Q1 (also listed) rather than substituting across grades.
