Single-gate open-drain buffer for mixed-voltage and wired-OR buses
The Texas Instruments SN74LVC1G07DBVTG4 is a single-gate buffer from the 74LVC family with a non-inverting, open-drain output. The open-drain output sinks up to 32 mA but does not source current — the load pulls the output high through an external resistor, which is the standard approach for wired-OR interrupt lines, I²C-style buses, or driving low-side loads like indicator LEDs. The single-element, single-bit-per-element configuration means one buffer per package — useful when you need exactly one open-drain stage without wasting a multi-gate device.
Open-drain output — what 32 mA sink means for the BOM
The 32 mA sink capability lets this buffer drive a heavier pull-down than a typical logic output — useful when discharging bus capacitance quickly or driving a low-impedance load.
Active lifecycle — no near-term BOM risk
For a production BOM, this means there is no last-time-buy horizon or obsolescence notice to plan around.
