NTS0102GD-Q100H

Translators, Level Shifters Overview

The NTS0102GD-Q100H is a dual-supply translating transceiver with auto direction sensing, designed for bidirectional voltage level translation. It features two 2-bit input-output ports (An and Bn), one output enable input (OE), and two supply pins (VCC(A) and VCC(B)). 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 maximum data rates of 50 Mbit/s in push-pull mode. It includes IOFF circuitry for partial power-down applications to prevent backflow current. Qualified to AEC-Q100 Grade 1 standards, it functions from -40 °C to +125 °C.

Translators, Level Shifters Procurement Notes

Verify the specific package type XSON8 (SOT996-2) matches the design footprint. Confirm the orderable part number NTS0102GD-Q100H corresponds to the required temperature range of -40 °C to +125 °C. Ensure the reel packing method aligns with assembly equipment specifications. Cross-reference the datasheet revision date to confirm the latest electrical characteristics are utilized.

Translators, Level Shifters Selection Notes

Select this component when designing systems requiring automatic direction sensing for bidirectional communication between disparate voltage levels. It is suitable for automotive applications due to its AEC-Q100 qualification. Consider the open-drain nature of the transceiver for I2C or SMBus buses. Evaluate the internal pull-up resistors against external requirements to optimize signal integrity and power consumption.

Translators, Level Shifters Part Context

This device belongs to the NTS0102-Q100 family of dual-supply translating transceivers. It shares functional similarities with other members like the NTS0102DP-Q100 but differs in physical packaging. The GD variant utilizes an XSON8 package, offering a compact solution for space-constrained designs. It serves as a bridge for interfacing low-voltage controllers with higher-voltage peripherals in complex electronic architectures.

Translators, Level Shifters Replacement Considerations

The NTS0102TL-Q100H is a drop-in replacement for the NTS0102GD-Q100H. The TL package includes a center pad not present in the GD package. This pad is not electrically connected to the silicon. Designers must evaluate PCB layout risks regarding traces under the package area to avoid potential EMI or crosstalk issues during substitution.

Translators, Level Shifters FAQ

How does the device handle power-down conditions?

The NTS0102GD-Q100H includes IOFF circuitry that disables the outputs when either VCC(A) or VCC(B) is at ground level. This prevents damaging backflow current through the device during partial power-down scenarios.

What is the relationship between VCC(A) and VCC(B) voltages?

During normal operation, VCC(A) must be less than or equal to VCC(B). However, during power-up, either supply can ramp up first without damaging the device, as there is no special sequencing requirement.
