Single inverting open-drain buffer in a 1.4x0.9 mm DSBGA
The SN74LVC1G06YEAR: Operates from a 1.65V to 5.5V supply. The open-drain output sinks up to 32mA.
No official replacement part number is provided by the manufacturer, so a pin-compatible substitute must be validated against the original footprint and electrical requirements.
The open-drain output (no high-side driver) lets multiple outputs share a common pull-up resistor for wired-OR logic.
The wide supply range covers 1.8V, 2.5V, 3.3V, and 5V nominal rails. This lets a single line item serve across different voltage domains in a mixed-signal board, simplifying BOM management. The 74LVC family is known for 5V-tolerant inputs (when Vcc is lower), but the open-drain output means the pull-up rail can be higher than Vcc — handy for driving a 5V logic input from a 3.3V buffer.
