It takes one input and reproduces it at the output with push-pull drive capable of sourcing or sinking 32mA per channel. The part operates across a supply range of 1.65V to 5.5V, which means it can sit on a 1.8V or 3.3V rail without needing a separate level translator — useful when bridging between an MCU's GPIO and a higher-voltage peripheral like a sensor or indicator LED. ## Supply voltage flexibility — no level shifter needed A 1.8V logic rail from a low-power MCU feeds directly into this buffer's VCC, and the output swings rail-to-rail, so a downstream 3.3V or 5V device sees a clean logic-high. That eliminates a discrete level-shifter IC or a resistor-divider network on each signal line. The same part also runs at 3.3V or 5V without modification, so it can be a common line item across multiple voltage domains in a design. ## Output drive — 32mA sink and source per channel With 32mA output current capability in both sink and source directions, this buffer can directly drive a low-current LED, a small relay coil through a base resistor, or the clock input of a high-impedance load. For a single-gate device in a 5-pin SC-70 package, that drive strength is notable — many competitors in the same footprint top out at 24mA or 16mA. It also provides clean signal buffering for long PCB traces or ribbon cables where the line capacitance would otherwise stretch the edge rate. The extended range also covers outdoor telecom base-station equipment and solar inverter control boards that sit in direct sunlight.","metaTitle":"SN74LVC1G34DCKRE4 Buffer, Non-Inverting, 1.65V-5.5V, SC-70-5","metaDescription":"Texas Instruments SN74LVC1G34DCKRE4 single-gate non-inverting buffer. 32mA output drive, 1.65V-5.5V supply, -40°C to 125°C.
