Push-Pull Level Shift
These Push-Pull Level Shifts are bidirectional voltage level translators without direction pin needed for push-pull applications, such as SPI.
They allow voltage-level translation between 1.2V~3.6V on A port and 1.65V~5.5V on B port (VCCA ≤ VCCB). This allows for universal low-voltage bidirectional translation between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage nodes.
