Pinout

The SN74AVCH1T45DCKR is a single-channel bidirectional voltage-level translator from Texas Instruments. It has a total of 6 pins.
Pin Functions:
1. A (Input/Output): This pin connects to the low-voltage side (e.g., 1.2V to 3.6V).
2. B (Input/Output): This pin connects to the high-voltage side (e.g., 3.0V to 5.5V).
3. OE (Output Enable): Active low input that enables or disables the translation functionality.
4. GND (Ground): Common ground reference for both sides.
5. VCCA (Power Supply for Low Voltage): Connects to the low-voltage supply.
6. VCCB (Power Supply for High Voltage): Connects to the high-voltage supply.
The device facilitates signal level shifting between different voltage domains, making it suitable for interfacing between components with varying supply voltages.
