NXS0104BQX

Specialty Logic Overview

The NXS0104BQX is a 4-bit dual supply translating transceiver with auto direction sensing, housed in a DHVQFN14 (SOT762-1) package. It enables 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 supports a maximum data rate of 24 Mbps and features IOFF circuitry for partial power-down applications. Operating temperatures are specified from -40 °C to +125 °C.

Specialty Logic Feature Summary

• Auto direction sensing eliminates the need for explicit direction control signals
• IOFF circuitry prevents damaging backflow current during partial power-down
• Internal 10 kΩ pull-up resistors on all I/O ports
• High ESD protection performance across multiple standards

Specialty Logic Applications

• Desktop PC
• Handset
• Smartphone
• Tablet

Specialty Logic Procurement Notes

Verify the ordering suffix 'BQX' corresponds to the DHVQFN14 package variant. Confirm that the specific reel or cut tape quantity matches project requirements. Ensure the temperature range specification aligns with the operational environment constraints. Cross-reference the manufacturer part number against official Nexperia documentation to validate authenticity.

Specialty Logic Selection Notes

Select this component when interfacing systems with distinct supply voltages requiring bidirectional translation. The open-drain architecture suits I2C or 1-wire buses. Verify that the required data rate does not exceed 24 Mbps. Ensure the application benefits from the integrated pull-up resistors and auto-direction sensing capabilities.

Specialty Logic Part Context

This device belongs to the NXS family of dual supply translating transceivers. It shares functional characteristics with other variants like NXS0104PW and NXS0104GU12, differing primarily in package type. The BQX suffix specifically denotes the DHVQFN14 form factor, designed for compact surface-mount applications.

Specialty Logic FAQ

How does the device handle partial power-down?

The IOFF circuitry disables the outputs when either supply is off, preventing damaging backflow current through the device.

What is the function of the OE pin?

A LOW level at the OE pin forces all I/Os into a high-impedance OFF-state.
