NTB0104BQ-Q100X

Translators, Level Shifters Overview

The NTB0104BQ-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 1.2 V and 3.6 V, while VCC(B) operates between 1.65 V and 5.5 V. The device supports data rates up to 100 Mbps at 3.3 V/5.0 V supplies. It is qualified to AEC-Q100 Grade 1 and specified for ambient temperatures from -40 °C to +125 °C.

Translators, Level Shifters 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 operation by disabling outputs to prevent damaging backflow current when supplies are off.
• Inputs accept voltages up to 5.5 V, allowing compatibility with higher voltage buses on the B side regardless of the A side supply.
• High ESD protection capabilities ensure robustness against electrostatic discharge events on both port sides.

Translators, Level Shifters Applications

• Voltage level-translation applications interfacing devices operating at different supply voltages
• Automotive electronic systems requiring AEC-Q100 qualified components
• Bidirectional communication between low-voltage nodes such as 1.2 V, 1.8 V, 3.3 V, and 5.0 V

Translators, Level Shifters Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the NTB0104 family includes multiple options like DHVQFN14 and WLCSP12. Confirm the temperature range specification aligns with the design requirements, noting that the BQ variant is specified up to +125 °C. Ensure the automotive qualification grade meets the target application standards before finalizing procurement.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between dissimilar voltage domains is required without complex direction control logic. It is suitable for designs needing high ESD immunity and partial power-down support. Consider the DHVQFN14 package for surface mount assembly if space allows, or evaluate other package options if form factor constraints differ. Verify that the driving source can provide the minimum required drive capability for reliable operation.

Translators, Level Shifters Part Context

This part belongs to the NTB0104-Q100 family of dual-supply translating transceivers manufactured by NXP Semiconductors. The family is designed for automotive and industrial applications requiring reliable voltage level shifting. The Q100 designation indicates automotive qualification, ensuring reliability under harsh environmental conditions typical in vehicle electronics.

Translators, Level Shifters Replacement Considerations

NXB0104BQ-Q100X is a comparable 2-channel translating transceiver from Nexperia. Note that channel count differs; verify interface width requirements. NTB0104UK-Q100 is an alternative package version within the same family offering identical electrical characteristics in a WLCSP12 footprint.
