Single-gate inverting buffer with 3-state — what it buys you
The Texas Instruments SN74LVC1G240DCKT is a single-gate inverting buffer with a 3-state output, part of the 74LVC logic family. It accepts supply voltages from 1.65V to 5.5V, making it a single-device solution for translating between 1.8V, 2.5V, 3.3V, and 5V logic domains without a separate level shifter. The inverting path (input high → output low) is useful for polarity correction, bus isolation, or driving active-low enables on a mixed-voltage board.
32 mA symmetric drive — not just a bus buffer
That is unusually strong for a single-gate LVC part in a 5-pin SC-70. It can directly drive a handful of CMOS loads, a status LED through a resistor, or a short PCB trace without an additional line driver. The 3-state control lets you float the output when the bus is held by another driver.
Rated for 125°C — industrial and automotive under-hood ready
That 125°C ceiling matters for engine-bay electronics, industrial motor drives that sit near the heat sink, or outdoor telecom enclosures in direct sun. A part rated only to 85°C would need derating or active cooling in those environments; this one does not.
SC-70-5 footprint — fits where SOIC-8 will not
The supplier device package is SC-70-5 (also known as SOT-353). That is a 5-pin, 2.0 mm × 1.25 mm body — roughly one-third the board area of a single-gate in a SOT-23-5. On a dense mixed-signal board or a portable device where every square millimetre is budgeted, this package lets you drop a logic function exactly where it is needed rather than routing to a distant octal buffer.
