NXB0102UNAZ

Translators, Level Shifters Overview

The NXB0102 is a dual supply translating transceiver with auto direction sensing and 3-state outputs. It features two 2-bit input-output ports (An and Bn), one output enable input (OE), and two supply pins (VCC(A) and VCC(B)). VCC(A) operates between 1.2 V and 3.6 V, while VCC(B) operates between 1.65 V and 5.5 V. The device supports bidirectional voltage level translation between low voltage nodes including 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V.

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates the need for an extra control signal to manage data flow direction.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent damaging backflow current.
• High ESD protection capabilities exceeding specified thresholds for HBM, CDM, and latch-up performance.

Translators, Level Shifters Applications

• Voltage level-translation applications interfacing devices operating at different supply voltages
• Partial power-down applications requiring IOFF functionality
• Systems requiring bidirectional data transfer between varying logic levels

Translators, Level Shifters Procurement Notes

Verify that the specific package variant matches the design requirements, as the component is available in VSSOP8, XSON8, and WLCSP8 configurations. Confirm that the application environment stays within the specified temperature ranges of -40 °C to +85 °C or -40 °C to +125 °C. Ensure that the OE pin is properly biased during power cycles to maintain the high-impedance OFF-state as recommended.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between dissimilar voltage domains is required without external direction control signals. It is suitable for designs needing robust ESD protection and partial power-down capabilities. Note that it is not recommended for open-drain applications like I2C due to its push-pull architecture; consider alternative translators for such 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 compact solution for connecting components across different power rails. The inclusion of auto-direction sensing simplifies PCB layout by removing the need for dedicated direction control lines, optimizing space in dense electronic assemblies.

Translators, Level Shifters FAQ

Can VCC(A) be higher than VCC(B) during normal operation?

No, during operation VCC(A) must never be higher than VCC(B). However, during power-up, either supply can ramp up first without damaging the device.

Is this device suitable for I2C bus applications?

No, the NXB0102 is not recommended for open-drain driver applications such as I2C. For these applications, the NXS0102 level translator is recommended instead.
