NTSX2102TLH

Translators, Level Shifters Overview

The NTSX2102TLH is a dual-supply translating transceiver featuring two bidirectional channels with auto direction sensing. It supports voltage translation between any nodes within the 1.65 V to 5.5 V range, including 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The device utilizes open-drain outputs and includes IOFF circuitry for partial power-down applications. It operates across an ambient temperature range of -40 °C to +85 °C and is housed in an XSON8 package (SOT1052-2).

Translators, Level Shifters Feature Summary

• Auto direction sensing eliminates the need for explicit control signals to manage data flow.
• IOFF circuitry prevents damaging backflow currents during partial power-down states.
• Wide supply voltage flexibility allows translation between multiple standard logic levels.

Translators, Level Shifters Applications

• I2C/SMBus bus level translation
• UART interface voltage adaptation
• General Purpose Input/Output (GPIO) interfacing

Translators, Level Shifters Procurement Notes

Verify that the specific TL ordering suffix corresponds to the XSON8 package variant when sourcing. Confirm compliance with RoHS and REACH standards as indicated in the manufacturer's material declaration. Ensure the procurement channel provides valid traceability documentation for active components.

Translators, Level Shifters Selection Notes

Select this component for designs requiring bidirectional translation without dedicated direction control pins. Verify that the application does not exceed the maximum capacitive load limits to ensure proper one-shot circuit triggering. Consider the OE pin configuration requirements for power-up sequences.

Translators, Level Shifters Part Context

This part belongs to the NTSX2102 family of dual-supply translators. It serves as a drop-in replacement for the GD package variant on PCB layouts where no traces exist under the center pad. The TL package features a center pad that is not electrically connected to the silicon die.

Translators, Level Shifters Replacement Considerations

The datasheet identifies NTSX0102TLH as a direct drop-in replacement for the NTSX2102 series.

Translators, Level Shifters FAQ

How does the device handle partial power-down conditions?

The integrated IOFF circuitry automatically disables the outputs to prevent damaging backflow current when either supply voltage is at ground potential.

Is an external direction control signal required?

No, the device employs auto direction sensing to determine the data flow direction between ports A and B automatically.
