NXU0102GXX

Translators, Level Shifters Overview

The NXU0102GXX is a 2-bit dual-supply level translating buffer with Schmitt-trigger inputs and 3-state outputs. It facilitates asynchronous communication between data buses, transmitting data unidirectionally from the A bus to the B bus on two channels. Both VCCA and VCCB support supply voltages ranging from 0.9 V to 5.5 V, enabling translation between standard voltage nodes including 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The device ensures low static and dynamic power consumption across the entire supply range and is fully specified for partial power-down applications using IOFF circuitry.

Translators, Level Shifters Feature Summary

• Schmitt-trigger inputs with integrated static high ohmic pull-down resistors prevent undefined states and provide tolerance for slow or noisy input signals.
• IOFF circuitry prevents potentially damaging backflow current when powered down or if a power supply is disconnected, supporting partial power-down mode operation.
• Output enable (OE) pin allows connection to either the VCCA or VCCB domain, providing design flexibility for isolating buses during power transitions.
• Suspend mode activates when either supply voltage drops below 100 mV or becomes floating, ensuring outputs enter a high-impedance OFF-state.

Translators, Level Shifters Applications

• General purpose I/O level translation
• Supporting push-pull voltage translation for 2-wire UART and 2-pin JTAG protocols
• Operation in noisy environments or with slow input signals
• Consumer electronics

Translators, Level Shifters Procurement Notes

Verify the specific package suffix matches the required form factor, as the GXX designation corresponds to the X2SON8 package (SOT1233-2). Confirm that the thermal enhanced characteristics of this package align with your board's thermal management strategy. Ensure the ordering information table in the datasheet is referenced for exact temperature ranges and marking codes associated with this variant.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation is not required, as data flow is fixed from A to B. Consider the X2SON8 package for designs needing thermal enhancement in a small footprint. Verify that the OE pin logic aligns with the system's power-up sequence requirements. Check if the 2-channel capacity meets the interface needs without requiring additional components.

Translators, Level Shifters Part Context

This device belongs to Nexperia's NXU series of dual-supply buffers. It shares functional similarities with the NXU0202 but offers a 2-bit configuration instead of 4-bit. The product family supports various packages including VSSOP8, XSON8, and X2SON8, allowing designers to choose based on space and thermal constraints while maintaining consistent electrical performance across the series.
