NXS0104UMZ

Translators, Level Shifters Overview

The NXS0104UMZ is a 4-bit dual supply translating transceiver with auto direction sensing, housed in a WLCSP12 package (SOT8019-1). It supports bidirectional voltage level translation between VCC(A) ranging from 1.65 V to 3.6 V and VCC(B) ranging from 2.3 V to 5.5 V. The device features an open-drain output structure and includes IOFF circuitry for partial power-down applications. It operates within a temperature range of -40 °C to +125 °C and supports data rates up to 24 Mbps.

Translators, Level Shifters Feature Summary

• Auto direction sensing enables bidirectional voltage level translation without explicit direction control signals.
• IOFF circuitry disables outputs during partial power-down to prevent damaging backflow currents.
• Open-drain architecture with internal pull-up resistors suitable for I2C and 1-wire interfaces.

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix UMZ corresponds to the WLCSP12 package configuration as defined in the official Nexperia datasheet. Confirm that the required temperature grade and automotive qualification standards align with the project specifications before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring interface between logic families operating at different supply voltages, specifically where VCC(A) must not exceed VCC(B). Ensure the application utilizes open-drain drivers or accepts the open-drain output characteristics provided by this transceiver.

Translators, Level Shifters Part Context

This part belongs to the NXS0104 family of dual supply translating transceivers manufactured by Nexperia. The UMZ suffix identifies the specific WLCSP12 wafer level chip-scale package variant, distinguishing it from other package options like TSSOP14 or DHVQFN14 within the same functional family.

Translators, Level Shifters FAQ

What is the function of the OE pin?

The OE (Output Enable) pin controls the state of the I/O ports. A LOW level on OE causes all outputs to assume a high-impedance OFF-state.

How does the device handle partial power-down?

The integrated IOFF circuitry detects when either VCC(A) or VCC(B) is at ground potential and disables the outputs to prevent damaging backflow current through the device.
