NXB0104GU12X

Translators, Level Shifters Overview

The NXB0104GU12X is a 4-bit dual supply translating transceiver with auto direction sensing and 3-state outputs, housed in an XQFN12 package (SOT1174-1). It supports bidirectional voltage level translation between VCC(A) ranging from 1.2 V to 3.6 V and VCC(B) ranging from 1.65 V to 5.5 V. The device features IOFF circuitry for partial power-down applications, preventing backflow current. Recommended operating conditions specify an ambient temperature range of -40 °C to +125 °C.

Translators, Level Shifters Feature Summary

• Auto direction sensing enables bidirectional data flow without external control signals
• IOFF circuitry provides partial power-down mode operation to prevent damaging backflow currents
• Inputs accept voltages up to 5.5 V regardless of the associated supply rail
• High ESD protection capabilities exceeding specified HBM and CDM standards

Translators, Level Shifters Applications

• Interfacing systems operating at different low voltage nodes such as 1.2 V, 1.8 V, 3.3 V, and 5.0 V
• Partial power-down applications requiring isolation during power-off states
• Bus interfaces where automatic direction detection is required for data transfer

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple packages including TSSOP14, DHVQFN14, and XQFN12. Confirm that the XQFN12 variant corresponds to the SOT1174-1 designation. Ensure the selected component meets the required temperature range specifications for the intended application environment before procurement.

Translators, Level Shifters Selection Notes

Select this component when designing circuits requiring bidirectional translation between distinct voltage domains without manual direction control. It is suitable for interfacing logic families across various low voltage nodes. Note that it is not recommended for open-drain applications like I2C due to its output architecture; consider alternative translators for those specific bus types.

Translators, Level Shifters Part Context

This device belongs to Nexperia's family of translating transceivers designed for mixed-voltage system integration. It provides a solution for connecting components with incompatible supply voltages while maintaining signal integrity. The inclusion of auto direction sensing simplifies board design by eliminating the need for separate direction control pins compared to traditional transceivers.

Translators, Level Shifters FAQ

Can VCC(A) be powered higher than VCC(B)?

During normal operation, VCC(A) must be less than or equal to VCC(B). However, during power-up, either supply can ramp up first without damaging the device.

Is this device suitable for I2C buses?

No, the NXB0104 is not recommended for open-drain driver applications such as I2C. The NXS0104 level translator is recommended for those applications.
