Pinout
1. VCCA (Pin 1): Supply voltage for the A-side. This can typically range from 1.2V to 3.6V.
2. DIR (Pin 2): Direction control pin. Determines the data flow direction. When DIR is high, data flows from A to B. When DIR is low, data flows from B to A.
3. A (Pin 3): A-side input/output.
4. GND (Pin 4): Ground reference for both sides.
5. B (Pin 5): B-side input/output.
6. OE (Pin 6): Output enable pin. When high, the device is disabled; when low, it is enabled.
7. VCCB (Pin 8): Supply voltage for the B-side. This can typically range from 1.2V to 5.5V.
The device is designed to translate signals between different voltage levels, making it versatile for interfacing with mixed-voltage systems.
