Single-bit inverting buffer for low-voltage buses
The SN74AUC1G240DBVR is a single-bit inverting buffer with 3-state output from Texas Instruments' 74AUC family, designed for 0.8V to 2.7V supply rails — the sub-1V floor makes it a fit for the latest low-power SoC and FPGA I/O banks where traditional 1.8V logic would overdrive the input. Housed in a 5-pin SOT-23-5 (SC-74A) package, it occupies roughly 3 mm² of board area, which matters when the layout is routing dense BGA escape traces and every via counts.
Output drive and signal-integrity budget
Each output sources or sinks 9 mA — at 1.2 V supply the edge rate into a 15 pF load is fast enough to toggle a downstream SPI clock at tens of MHz, but the 3-state enable (OE) lets multiple buffers share a common data line without contention. The industrial temperature range from -40°C to 85°C covers most embedded and communications equipment; the part does not carry AEC-Q100 qualification, so it is not specified for under-hood automotive duty.
Lifecycle and compliance
The part is available in Tape & Reel or Cut Tape options, which aligns with standard pick-and-place assembly and prototype builds alike.
