NXS0104BQ-Q100X

Specialty Logic Overview

The NXS0104BQ-Q100X is a 4-bit dual supply translating transceiver with auto direction sensing, enabling bidirectional voltage level translation. It features two 4-bit input-output ports (An and Bn), one output enable input (OE), and two supply pins (VCC(A) and VCC(B)). VCC(A) operates between 1.65 V and 3.6 V, while VCC(B) operates between 2.3 V and 5.5 V. The device supports a maximum data rate of 24 Mbps in push-pull mode. It includes IOFF circuitry for partial power-down applications to prevent backflow current. Qualified to AEC-Q100 Grade 1, it functions from -40 °C to +125 °C and is housed in a DHVQFN-14 package.

Specialty Logic Feature Summary

• Auto direction sensing eliminates the need for external control signals to manage data flow direction between voltage domains.
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent damaging backflow currents when supplies are off.
• Dual supply architecture allows flexible translation between various standard voltage nodes such as 1.8 V, 2.5 V, 3.3 V, and 5.0 V.
• Integrated internal pull-up resistors provide DC current sourcing capability for open-drain drivers without requiring external components.

Specialty Logic Applications

• I2C bus interface translation
• 1-wire protocol interface translation
• Point-to-point system interfacing between different voltage domains

Specialty Logic Procurement Notes

Verify the specific suffix Q100X indicates automotive qualification and reel packaging configuration. Confirm the DHVQFN-14 package variant matches the SOT762-1 outline dimensions. Ensure the ordering code aligns with the required temperature range of -40 °C to +125 °C. Cross-reference the manufacturer part number with official Nexperia documentation to validate authenticity and revision status before procurement.

Specialty Logic Selection Notes

Select this component for designs requiring bidirectional translation between low-voltage logic (1.65 V–3.6 V) and higher-voltage interfaces (2.3 V–5.5 V). It is suitable for I2C or 1-wire applications utilizing open-drain drivers. Consider the DHVQFN-14 package for space-constrained PCB layouts. Verify that the application does not require push-pull driving on both sides simultaneously, as the NXB0104-Q100 may be more appropriate for those specific scenarios.

Specialty Logic Part Context

This device belongs to the NXS0104-Q100 family of dual supply translating transceivers manufactured by Nexperia. The family includes variants with different package options, such as TSSOP14 and XQFN12, all sharing the same core functionality. These components are designed for automotive and industrial applications requiring reliable voltage level shifting between disparate digital systems.

Specialty Logic FAQ

How does the device handle data direction?

The NXS0104BQ-Q100X uses auto direction sensing to automatically determine the direction of data flow between the A and B ports without requiring an external control signal.

What is the function of the OE pin?

The Output Enable (OE) pin controls the state of the I/O ports. When set to LOW, it forces all outputs into a high-impedance OFF-state.

Can this device be used with push-pull drivers?

Yes, it can be used with push-pull drivers, but the datasheet notes that the NXB0104-Q100 may be more suitable for applications specifically requiring push-pull output characteristics.
