NXB0108BQX

Translators, Level Shifters Overview

The NXB0108BQX is an 8-bit dual supply translating transceiver with auto direction sensing and 3-state outputs, manufactured by Nexperia USA Inc. It operates within a VCC(A) range of 1.2 V to 3.6 V and a VCC(B) range of 1.65 V to 5.5 V. The device supports data rates up to 110 Mbps at 3.3 V/5.0 V and features IOFF circuitry for partial power-down applications. It is housed in a 20-DHVQFN package (SOT764-1) and functions across an ambient temperature range of -40 °C to +125 °C.

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates the need for external control signals to manage bidirectional data flow between ports A and B.
• IOFF circuitry disables outputs during power-down states to prevent damaging backflow currents when either supply voltage is off.
• High electrostatic discharge protection capabilities exceeding specified JEDEC standards for both Human Body Model and Charged Device Model events.

Translators, Level Shifters Applications

• Voltage level translation between low voltage nodes such as 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V
• Interfacing system controllers with peripheral devices operating at different supply voltages
• Partial power-down mode operation in multi-supply systems

Translators, Level Shifters Procurement Notes

Verify that the specific ordering suffix matches the DHVQFN20 package configuration required for the design. Confirm the temperature grade corresponds to the -40 °C to +125 °C specification. Ensure input drivers meet the minimum ±2 mA drive capability requirement for correct operation. Check that pull-up or pull-down resistors on I/O lines exceed 50 kΩ to avoid output contention issues.

Translators, Level Shifters Selection Notes

Select this component for designs requiring automatic bidirectional translation without dedicated direction control pins. It is suitable for interfacing mixed-voltage logic families where VCC(A) must remain lower than or equal to VCC(B) during normal operation. Verify that the application does not require open-drain characteristics, as the device architecture is not recommended for protocols like I2C or 1-Wire.

Translators, Level Shifters Part Context

The NXB0108 series belongs to Nexperia's family of dual supply translating transceivers designed for complex multi-voltage environments. The BQ variant specifically denotes the DHVQFN20 package option, providing a compact footprint for space-constrained PCB layouts while maintaining thermal performance through the exposed pad.

Translators, Level Shifters FAQ

Can VCC(A) be powered before VCC(B)?

Yes, although VCC(A) should normally be less than or equal to VCC(B) during operation, the device is not damaged if VCC(A) ramps up first during power-up sequences.

Is this device suitable for I2C bus applications?

No, the NXB0108 is not recommended for open-drain driver applications such as I2C due to its output architecture; the NXS0108 is recommended for those use cases.
