SN74LV8T541-Q1

SN74LV8T541-Q1 is a Texas Instruments AEC-Q100 Grade 1 automotive octal buffer/driver with 3-state outputs and single-supply level translation — for automotive GPIO, bus driving and signal redriving where the sending and receiving logic run on different rails. The level translation is the selection point: reduced-threshold inputs plus 5.5 V-tolerant pins let one device translate up (1.2 V to 1.8 V, 1.5 V to 2.5 V, 1.8 V to 3.3 V, 3.3 V to 5.0 V) and down (5.0 V, 3.3 V and 2.5 V to 1.8 V; 5.0 V and 3.3 V to 2.5 V; 5.0 V to 3.3 V) with no second translator IC, across a 1.65 V to 5.5 V supply, at up to 150 Mbps with 5 V or 3.3 V VCC and 13.7 ns propagation delay. Eight non-inverting buffers share two active-low output-enable pins (both must be low for the outputs to be active), it uses the standard function pinout, offers latch-up performance above 250 mA per JESD 17, HBM ESD classification level 2 and CDM level C4B, and operates from -40°C to +125°C. Package options are 20-pin TSSOP, VSSOP and wettable-flank VQFN. Selection advice: choose the LV8T-Q1 when a design mixes voltage domains; if no translation is needed and the rail is 2 V to 5.5 V CMOS, the SN74AHC541-Q1 is the simpler alternative. For automotive assemblies requiring optical solder-joint inspection, specify the wettable-flank VQFN (RKS) ordering code. Parameters verified against Texas Instruments documentation.
