NXU0202DCH

Translators, Level Shifters Overview

The NXU0202DCH is a 2-bit dual-supply level translating buffer with Schmitt-trigger inputs and 3-state outputs. It facilitates asynchronous communication between data buses, supporting unidirectional translation from the A bus to the B bus on three channels and from the B bus to the A bus on one channel. Both VCCA and VCCB supply voltages range from 0.9 V to 5.5 V, enabling translation between nodes such as 1.2 V, 1.8 V, 3.3 V, and 5.0 V. The device features an output enable (OE) pin referenced to either domain, IOFF circuitry for partial power-down protection, and low static power consumption of 3 µA at +25 °C.

Translators, Level Shifters Feature Summary

• Dual-supply operation supports voltage ranges from 0.9 V to 5.5 V on both VCCA and VCCB domains.
• Schmitt-trigger inputs include integrated high-ohmic pull-down resistors to prevent undefined states.
• IOFF circuitry prevents backflow current during partial power-down or floating supply conditions.
• Output enable (OE) allows connection to either VCCA or VCCB domain for flexible control.

Translators, Level Shifters Applications

• General purpose I/O level translation
• Supporting push-pull voltage translation for 2-wire UART and 2-pin JTAG protocols
• Noisy environments or slow input signals

Translators, Level Shifters Procurement Notes

Verify the specific package suffix DCH corresponds to the SOT765-1 (VSSOP8) plastic very thin shrink small outline package with an 8-lead body width of 2.3 mm. Confirm the temperature range matches the specified -40 °C to +125 °C operational limits. Ensure the ordering information aligns with the manufacturer's current product data sheet revision to avoid discrepancies in marking codes or functional specifications.

Translators, Level Shifters Selection Notes

Select this component when interfacing between different voltage domains requiring bidirectional capability on select channels and unidirectional on others. The integrated Schmitt triggers make it suitable for noisy environments. Verify that the required data rate does not exceed the maximum specified for the target voltage translation pair. Consider the VSSOP8 package constraints regarding thermal resistance and board space availability.

Translators, Level Shifters Part Context

This part belongs to the NXU0202 family of 2-bit dual-supply buffers. It shares functional similarities with the NXU0102 but offers distinct channel configurations. The DCH suffix specifically denotes the VSSOP8 package variant within the broader Nexperia logic IC portfolio designed for voltage level translation applications.
