NXB0108BQ-Q100X

Translators, Level Shifters Overview

The NXB0108BQ-Q100X is an 8-bit dual supply translating transceiver with auto direction sensing and 3-state outputs, housed in a DHVQFN20 package. It supports VCC(A) from 1.2 V to 3.6 V and VCC(B) from 1.65 V to 5.5 V. Propagation delay ranges from 0.2 ns to 11.9 ns depending on voltage and temperature. Data rates reach up to 110 Mbps at 3.3 V/5.0 V. Operating temperatures span -40 °C to +125 °C. The device features IOFF circuitry for partial power-down applications.

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates the need for explicit control signals to manage data flow between ports.
• IOFF circuitry prevents damaging backflow currents when either supply rail is powered down.
• Dual supply architecture enables translation between various low voltage nodes including 1.2 V, 1.8 V, 3.3 V, and 5.0 V.
• High ESD protection capabilities exceed standard requirements for both human body model and charged device model.

Translators, Level Shifters Applications

• Voltage level-translation applications interfacing devices operating at different supply voltages
• Automotive electronic systems requiring AEC-Q100 Grade 1 qualified components
• Partial power-down mode operations in battery-powered or multi-rail systems

Translators, Level Shifters Procurement Notes

Verify the specific suffix BQ corresponds to the DHVQFN20 package variant during ordering. Confirm that the Q100 designation aligns with automotive qualification requirements for your target application. Ensure supply voltage sequencing respects the operational limits defined in the datasheet, particularly regarding VCC(A) and VCC(B) relationships during power-up phases.

Translators, Level Shifters Selection Notes

Select this component when bidirectional translation between disparate voltage domains is required without external direction control logic. The DHVQFN20 package offers thermal enhancement suitable for compact designs. Consider the IOFF feature if system power management involves partial shutdown states. Verify input drive capability meets the minimum ±2 mA requirement for reliable operation across the specified temperature range.
