NXU0304BQ-Q100X

Translators, Level Shifters Overview

The NXU0304BQ-Q100X is a 4-bit dual-supply voltage level translating buffer with Schmitt-trigger inputs and 3-state outputs. It supports data rates up to 250 Mbps for translations between 1.8 V and 5 V. Supply voltages VCCA and VCCB range from 0.9 V to 5.5 V, accommodating nodes such as 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The device operates within an ambient temperature range of -40 °C to +125 °C and is housed in a DHVQFN-14 package (SOT762).

Translators, Level Shifters Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards.
• Integrated IOFF circuitry prevents backflow current during partial power-down or floating supply conditions.
• Schmitt-trigger inputs with static high ohmic pull-down resistors ensure noise tolerance for slow input signals.
• Output enable pin allows connection to either VCCA or VCCB domain for flexible bus isolation.

Translators, Level Shifters Applications

• General purpose I/O level translation
• Push-pull voltage translation for UART, SPI, and JTAG protocols
• Noisy environments or applications with slow input signals

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the Q100 designation aligns with automotive grade requirements. Ensure the DHVQFN-14 footprint corresponds to the SOT762-1 mechanical drawing. Check thermal derating specifications against the expected operating environment.

Translators, Level Shifters Selection Notes

Select this component when asynchronous communication between buses with different voltage domains is required. The device is suitable for designs needing low standby current and protection against supply transitions. Consider the output drive capability and propagation delay characteristics relative to the target data rate and load capacitance.

Translators, Level Shifters Part Context

This part belongs to the NXU0x04 family of voltage level translators manufactured by Nexperia. It shares functional similarities with the NXU0104 and NXU0204 models but provides four channels. The product line is designed to facilitate interface connections across various logic families and voltage levels in consumer and automotive electronics.

Translators, Level Shifters FAQ

How does the device handle floating power supplies?

If either VCCA or VCCB drops below 100 mV or becomes disconnected, the device enters suspend mode, placing all outputs in a high-impedance state.

What is the function of the OE pin?

The Output Enable (OE) pin controls the state of the outputs. When set LOW, the outputs are disabled and enter a high-impedance OFF-state to isolate the buses.
