NXB0104BQ-Q100X

Translators, Level Shifters Overview

The NXB0104BQ-Q100X is a dual-supply translating transceiver with auto direction sensing and three-state outputs. It features four bidirectional data ports (An, Bn), one output enable input (OE), and two supply pins (VCC(A) and VCC(B)). VCC(A) operates between 1.2 V and 3.6 V, while VCC(B) operates between 1.65 V and 5.5 V. The device supports partial power-down applications using IOFF circuitry. It is qualified to AEC-Q100 Grade 1 standards for automotive use.

Translators, Level Shifters Feature Summary

• Auto direction sensing enables bidirectional voltage level translation without external control signals
• IOFF circuitry provides partial power-down mode operation by disabling outputs to prevent backflow current
• Automotive product qualification in accordance with AEC-Q100 Grade 1 standard
• Wide supply voltage range supporting multiple low voltage nodes from 1.2 V to 5.5 V

Translators, Level Shifters Applications

• Interfacing devices or systems operating at different supply voltages
• Automotive electronic applications requiring AEC-Q100 Grade 1 qualification
• Partial power-down applications utilizing IOFF circuitry

Translators, Level Shifters Procurement Notes

Verify the specific package type DHVQFN-14 (SOT762-1) matches your PCB footprint requirements. Confirm that the AEC-Q100 Grade 1 qualification meets your automotive application standards. Ensure supply voltage sequencing respects the operational limits where VCC(A) must not exceed VCC(B) during normal operation. Check datasheet specifications for thermal derating characteristics relevant to your enclosure design.

Translators, Level Shifters Selection Notes

Select this component when interfacing logic families with differing supply voltages, specifically between the 1.2 V–3.6 V and 1.65 V–5.5 V ranges. The auto-direction sensing feature simplifies design by eliminating the need for separate direction control pins. Consider the DHVQFN-14 package for compact surface-mount layouts requiring side-wettable flanks for automated optical inspection. Verify that the driving source can provide the minimum required ±2 mA drive capability for correct operation.

Translators, Level Shifters Part Context

The NXB0104-Q100 series includes variants such as NXB0104PW-Q100J in TSSOP-14 and NXB0104GU12-Q100 in XQFN-12 packages. All variants share the same core functionality of dual-supply translating transceivers with auto direction sensing. The BQ suffix specifically denotes the DHVQFN-14 package option. These components are part of Nexperia's automotive-grade logic portfolio designed for robust performance in demanding environments.

Translators, Level Shifters FAQ

What is the function of the OE pin?

The OE pin is an output enable input referenced to VCC(A). Setting OE to LOW causes all I/Os to assume a high-impedance OFF-state.

How does the device handle power-down conditions?

The device includes IOFF circuitry that disables the output when either VCC(A) or VCC(B) is switched off, preventing damaging backflow current through the device.

Is there a specific power-up sequence required?

No special power-up sequencing is required. During power-up, VCC(A) ≥ VCC(B) does not damage the device, although VCC(A) must not exceed VCC(B) during normal operation.
