The NXS0108-Q100, developed by Nexperia, provides a simple yet powerful solution to this problem. It is an 8-bit bidirectional voltage-level translator specifically designed and qualified for automotive applications, offering reliability, high-speed performance, and full compliance with AEC-Q100 standards.
1. What is the NXS0108-Q100?
The NXS0108-Q100 is an automotive-grade dual-supply voltage-level translator that enables safe and efficient signal interfacing between circuits operating at different logic levels. It supports voltage translation between 1.2 V to 3.6 V on one side (VCCA) and 1.65 V to 5.5 V on the other (VCCB), making it ideal for bridging low-power microcontrollers with higher-voltage peripherals in vehicle electronic control units (ECUs).
With eight bidirectional channels, the device can translate data, address, or control signals in both directions without additional control logic. This makes it a perfect fit for bus-oriented interfaces such as I²C, SPI, UART, and general-purpose I/O lines.

- Compact Package: Offered in TSSOP20 and DHVQFN20 (3 mm × 3 mm) packages, optimizing board space and layout efficiency.
3. Typical Automotive Applications
The NXS0108-Q100 is widely used in automotive electronics, where multiple logic voltage levels coexist within complex subsystems. Some common applications include:
- Body control modules (BCM): Connecting 3.3 V microcontrollers with 5 V sensor or actuator interfaces.
- Infotainment and telematics units: Interfacing low-voltage processors with legacy CAN or LIN transceivers.
- ADAS systems: Voltage translation between AI processors, radar/LiDAR sensors, and data acquisition modules.
- Instrument clusters: Synchronizing logic signals between mixed-voltage display drivers and control logic.
By providing a simple drop-in solution for logic level mismatch, the NXS0108-Q100 reduces design complexity and enhances signal reliability across temperature ranges from –40 °C to +125 °C.
