NTS0102TL-Q100H

Translators, Level Shifters Overview

The NTS0102TL-Q100H is a dual supply translating transceiver with open-drain outputs and auto direction sensing. It features two 2-bit input-output ports (An, Bn) and an 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 bidirectional voltage level translation between nodes such as 1.8 V, 2.5 V, 3.3 V, and 5.0 V. Maximum data rates reach 50 Mbit/s in push-pull mode. It includes IOFF circuitry for partial power-down applications to prevent backflow current.

Translators, Level Shifters Feature Summary

• Auto direction sensing enables bidirectional voltage level translation without explicit direction control signals.
• IOFF circuitry provides partial power-down mode operation by disabling outputs to prevent damaging backflow currents.
• Inputs accept voltages up to 5.5 V, ensuring compatibility across different voltage domains.
• Robust ESD protection meets HBM Class 2 standards exceeding 2500 V for the A port.

Translators, Level Shifters Applications

• I2C/SMBus interfaces
• UART connections
• GPIO expansion

Translators, Level Shifters Procurement Notes

Verify the specific ordering part number NTS0102TL-Q100H against official NXP documentation to confirm package type and temperature range specifications. Ensure compliance with RoHS and REACH requirements as indicated in the product data sheet. Cross-reference the SOT1052-2 package details for accurate PCB layout implementation.

Translators, Level Shifters Selection Notes

Select this component when interfacing systems operating at different supply voltages requiring open-drain or push-pull drivers. Consider the wide supply voltage ranges of VCC(A) and VCC(B) for flexible design integration. Evaluate the auto direction sensing capability to simplify interface logic. Verify that the maximum data rate requirements align with the specified 50 Mbit/s limit.

Translators, Level Shifters Part Context

The NTS0102 series comprises dual supply translating transceivers designed for voltage level shifting. The NTS0102TL variant utilizes the XSON8 plastic extremely thin small outline package (SOT1052-2). This family is suitable for point-to-point applications connecting devices with disparate voltage levels.

Translators, Level Shifters Replacement Considerations

The NTS0102GD can be replaced by the NTS0102TL. The TL package includes a center pad not electrically connected to silicon, allowing it to drop onto GD PCB layouts if no traces exist underneath. Evaluate risks regarding EMI and crosstalk if traces are present under the replacement footprint.

Translators, Level Shifters FAQ

How does the device handle partial power-down conditions?

The IOFF circuitry disables the outputs when either VCC(A) or VCC(B) is powered down, preventing damaging backflow current through the device.

What is the function of the OE pin?

A LOW level at the OE pin causes all outputs to assume a high-impedance OFF-state, effectively disabling the device.
