NTB0104UK-Q100Z

Translators, Level Shifters Overview

The NTB0104UK-Q100Z 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), an output enable input (OE), and supply pins VCC(A) and VCC(B). VCC(A) operates between 1.2 V and 3.6 V, while VCC(B) ranges from 1.65 V to 5.5 V. The device supports partial power-down applications via IOFF circuitry, preventing backflow current when powered down. Qualified to AEC-Q100 Grade 1, it functions within temperature ranges of -40 °C to +85 °C and -40 °C to +125 °C.

Translators, Level Shifters Feature Summary

• Auto direction sensing enables seamless bidirectional data flow without external control signals.
• IOFF circuitry ensures safe partial power-down operation by disabling outputs and preventing damaging backflow currents.
• Automotive qualification in accordance with AEC-Q100 Grade 1 standard for reliable performance in vehicle environments.
• Robust ESD protection capabilities exceeding specified thresholds for both Human Body Model and Machine Model standards.

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 buses connecting low-voltage nodes such as 1.2 V, 1.8 V, 3.3 V, and 5.0 V

Translators, Level Shifters Procurement Notes

Verify the specific package variant, WLCSP12, matches your board design constraints. Confirm that the automotive grade qualification aligns with your system requirements. Ensure supply voltage sequencing respects the operational limits where VCC(A) must not exceed VCC(B) during normal operation. Check pin compatibility for the OE and I/O connections against your schematic.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between distinct voltage domains is required without complex direction control logic. The wide supply range accommodates various low-voltage nodes. Consider the WLCSP12 package if space efficiency is critical. Verify that the input drive capability meets the minimum requirement for proper signal integrity across the translated interfaces.

Translators, Level Shifters Part Context

This part belongs to NXP's NTB0104-Q100 family of dual-supply translating transceivers. It shares core functionality with variants like the NTB0104BQ-Q100 but differs in packaging. The UK suffix denotes the WLCSP12 wafer-level chip-size package, offering a compact footprint suitable for dense PCB layouts compared to leaded or QFN alternatives.

Translators, Level Shifters Replacement Considerations

NTB0104BQ-Q100 offers identical electrical specifications and automotive qualification but utilizes a DHVQFN14 package instead of WLCSP12. Designers must verify mechanical fit and soldering process compatibility before substituting packages.

Translators, Level Shifters FAQ

Does the device require power-up sequencing?

No special power-up sequencing is required. Either power supply can be ramped up first without damaging the device, although VCC(A) must not exceed VCC(B) during normal operation.

How is the high-impedance state maintained during power transitions?

The OE pin should be tied to GND through a pull-down resistor to ensure the high-impedance OFF-state during power-up or power-down, preventing unintended bus activity.
