Single-gate open-drain inverter for mixed-voltage buses
The SN74LVC1G06DBVRG4: Operates from a 1.65V to 5.5V supply. The open-drain output sinks up to 32 mA.
The wide supply range covers 1.8V, 2.5V, 3.3V, and 5V logic rails without needing a separate level shifter. Input logic levels are specified relative to VCC: low-level threshold from 0.58V to 1.65V, high-level from 1.07V to 3.85V, ensuring compatibility with both lower-voltage and higher-voltage logic families. Quiescent current is a maximum of 10 µA, negligible for power budgets.
