NXU0202GTX

Translators, Level Shifters Overview

The NXU0202GTX is a 2-bit dual-supply level translating buffer with Schmitt-trigger inputs and 3-state outputs, manufactured by Nexperia. It operates within a supply voltage range of 0.9 V to 5.5 V for both VCCA and VCCB domains. The device supports maximum data rates up to 250 Mbps when translating between 1.8 V and 5 V. It features an output enable (OE) pin, IOFF circuitry for partial power-down protection, and low static current consumption of 3 µA at +25 °C. The component is housed in an XSON8 package (SOT833-1) and functions across an ambient temperature range of -40 °C to +125 °C.

Translators, Level Shifters Feature Summary

• Dual-supply architecture supporting independent voltage levels from 0.9 V to 5.5 V on separate A and B buses.
• Integrated IOFF circuitry prevents backflow current during power-down or floating supply conditions.
• Schmitt-trigger inputs provide noise immunity and tolerance for slow input signal transitions.
• Output enable control allows bus isolation via high-impedance state management.

Translators, Level Shifters Applications

• General purpose I/O level translation
• Supporting push-pull voltage translation for 2-wire UART protocols
• Supporting push-pull voltage translation for 2-pin JTAG protocols
• Consumer electronics requiring asynchronous communication

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'GTX' corresponds to the XSON8 package (SOT833-1) as defined in the manufacturer's documentation. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Ensure design compatibility with the 0.9 V to 5.5 V supply voltage constraints for both VCCA and VCCB pins prior to integration.

Translators, Level Shifters Selection Notes

Select this component when interfacing logic families requiring bidirectional or unidirectional translation between disparate voltage domains such as 1.2 V, 1.8 V, 3.3 V, and 5.0 V. The inclusion of Schmitt triggers makes it suitable for noisy environments. Consider the XSON8 package dimensions if board space is constrained, and verify that the 250 Mbps data rate requirement is met by the specific voltage translation scenario.

Translators, Level Shifters Part Context

The NXU0202 belongs to Nexperia's family of 2-bit dual-supply buffers designed for voltage level translation. It shares functional similarities with the NXU0102 but offers enhanced drive capabilities and specific package options like the XSON8. This series addresses the need for reliable communication between different voltage nodes without requiring complex external components or power sequencing.

Translators, Level Shifters FAQ

How does the NXU0202 handle power-down scenarios?

The device utilizes IOFF circuitry to prevent damaging backflow current when powered down or if one supply is disconnected. If either VCCA or VCCB drops below 100 mV or floats, the device enters a suspend mode with high-impedance outputs.

What is the function of the OE pin?

The Output Enable (OE) pin controls the state of the outputs. When set LOW, the outputs enter a high-impedance OFF-state, isolating the buses. The OE pin can be referenced to either the VCCA or VCCB domain.
