Single open-drain buffer with AEC-Q100 qualification
This allows the part to serve as a level translator or signal buffer in mixed-voltage automotive ECU, ADAS sensor, and body-control module designs without needing a separate translator IC. The open-drain output sinks up to 32 mA, sufficient to drive LEDs, small relays, or pull-down termination resistors directly. When the output is high, the drain floats; an external pull-up resistor sets the high-level voltage, enabling the buffer to translate between different supply domains on the same net.
Package and footprint for automotive PCB layout
Housed in a 5-pin SC-70 (SOT-353) package, the SN74LVC1G07QDCKTQ1 occupies minimal board area — roughly 2.0 mm × 2.1 mm. The SC-70 footprint is shared across the 74LVC1Gxx family, so a single land pattern can accommodate multiple logic functions during layout. Mounting is surface-mount only. The small body and fine pitch require standard reflow profiling; the part is not moisture-sensitive beyond typical MSL 1 for this package type, but verify the reel date code if the tape has been open for extended periods.
