Overview
The FXMA108BQX, produced by onsemi, is a configurable dual-voltage supply translator designed for both unidirectional and bidirectional voltage translation between two logic levels. This device allows translation between voltages as high as 5.5 V and as low as 1.65 V, making it versatile for various applications. The FXMA108BQX features auto-direction sensing, eliminating the need for a direction control pin, and supports power-up sequences where either VCC can be powered up first. It also includes 3-state outputs and power-off protection, ensuring reliable operation in diverse environments.

Key Features
- Bi-Directional Interface: Supports voltage translation between two levels from 1.65 V to 5.5 V.
- Configurable Inputs and Outputs: Inputs and outputs track VCC levels.
- Non-Preferential Power-Up: Either VCC can be powered up first.
- 3-State Outputs: Outputs remain in 3-state until active VCC level is reached and switch to 3-state if either VCC is at GND.
- Power-Off Protection: Internal power-down control circuits protect the device.
- Bus Hold on Data Inputs: Eliminates the need for pull-up resistors.
- Auto Direction Sensing: No direction control pin needed; the device automatically senses input transitions.
