Single-channel level-translating buffer in a five-pin SOT-23-5
The Texas Instruments SN74LV1T34DBVR is a single-element, non-inverting buffer from the 74LV series, housed in a SOT-23-5 surface-mount package. The push-pull output delivers 8 mA in both the high and low states, enough to drive a few CMOS inputs or a short trace.
Supply voltage range — the reason you spec this over a fixed-level buffer
A standard 5 V buffer won't work at 1.8 V, and a 3.3 V part won't tolerate a 5 V rail. This part covers all three common logic levels, so a single BOM line handles mixed-voltage interfaces — for example, a 3.3 V MCU talking to a 5 V sensor or a 1.8 V FPGA I/O bank. The 8 mA symmetrical drive keeps the output rise and fall times balanced, which simplifies timing closure on a shared bus.
The ROHS3 compliance covers the EU directive requirements for lead-free assembly. For procurement planning, this is a part you can stock with confidence — no urgent LTB math needed.
