NTS0102DP,125

Translators, Level Shifters Overview

The NTS0102DP,125 is a dual-supply translating transceiver with auto direction sensing and open-drain outputs. It features two bidirectional data ports (An, Bn) and an active HIGH output enable input (OE). Supply voltage VCC(A) operates between 1.65 V and 3.6 V, while VCC(B) operates between 2.3 V and 5.5 V. The device supports push-pull data rates up to 50 Mbit/s and includes IOFF circuitry for partial power-down applications. It is housed in an 8-lead TSSOP package and specified for ambient temperatures from -40 °C to +125 °C.

Translators, Level Shifters Feature Summary

• Auto direction sensing enables bidirectional voltage level translation without explicit control signals.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow current.
• Inputs accept voltages up to 5.5 V, supporting various low-voltage nodes.

Translators, Level Shifters Applications

• I2C/SMBus interfaces
• UART connections
• GPIO expansion

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix '125' corresponds to the TSSOP8 package and reel packing method. Confirm that the required temperature range of -40 °C to +125 °C matches the application environment. Ensure the design accommodates the dual supply requirements where VCC(A) must not exceed VCC(B) during normal operation.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems operating at different supply voltages, such as 1.8 V to 3.3 V or 3.3 V to 5.0 V. The device is suitable for point-to-point applications requiring open-drain drivers. For push-pull driver applications, verify if the NTB0102 is more appropriate based on specific performance needs.

Translators, Level Shifters Part Context

This part belongs to the NTS0102 family of dual-supply translating transceivers. It shares functional characteristics with other packages like XSON8 but differs in physical dimensions and pin configuration. The DP variant specifically utilizes the TSSOP8 plastic thin shrink small outline package.

Translators, Level Shifters Replacement Considerations

The NTS0102TLH is listed as a drop-in replacement for the GD package variant. Verify PCB layout compatibility regarding center pads and trace routing before substituting packages within the same product family.

Translators, Level Shifters FAQ

How does the device handle power-down conditions?

The NTS0102 includes IOFF circuitry that disables all output ports when either VCC(A) or VCC(B) is switched off, preventing damaging backflow current through the device.

What is the function of the OE pin?

The Output Enable (OE) pin controls the state of the I/Os. A LOW level causes all outputs to assume a high-impedance OFF-state, while a HIGH level enables normal operation.
