NXS0108BQX

Translators, Level Shifters Overview

The NXS0108BQX is an 8-bit dual supply translating transceiver with auto direction sensing, housed in a 20-DHVQFN package. It enables bidirectional voltage level translation between VCCA (1.2 V to 3.6 V) and VCCB (1.65 V to 5.5 V). The device features open-drain outputs, IOFF circuitry for partial power-down applications, and supports data rates up to 110 Mbps. It operates within 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 data flow direction.
• IOFF circuitry prevents damaging backflow currents when the device is powered down.
• Supports bidirectional translation between multiple standard voltage nodes including 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V.

Translators, Level Shifters Procurement Notes

Verify that the BQ suffix corresponds to the DHVQFN20 package variant. Confirm the specific temperature grade matches system requirements, as the datasheet specifies operation from -40 °C to +125 °C for this part number. Ensure input voltage levels on both ports remain within the specified absolute maximum ratings to prevent damage.

Translators, Level Shifters Selection Notes

Select this component for interfaces requiring open-drain compatibility and automatic direction detection. It is suitable for I2C or 1-wire protocols connecting devices with different supply voltages. Verify that the required data rate does not exceed the specified limits for the target voltage configuration and temperature range.

Translators, Level Shifters Part Context

The NXS0108 series includes variants such as NXS0108PW in a TSSOP20 package. The NXS0108BQX specifically utilizes the DHVQFN20 package type. All variants share the same functional description and electrical characteristics, differing primarily in physical packaging and thermal properties.

Translators, Level Shifters FAQ

How does the device handle direction control?

The NXS0108BQX uses auto direction sensing, meaning it automatically detects the direction of data flow without requiring an additional control signal.

What is the function of the IOFF circuitry?

The IOFF circuitry disables the outputs to prevent damaging backflow current through the device when it is in a partial power-down state.
