Introduction to Logic - Translators, Level Shifters

Logic-translators, or level-shifters, are electronic devices that allow different types of signals or systems to communicate with each other. They are typically used to convert a signal or data transmission from one voltage level to another. This allows two systems running on different voltage levels to communicate with one another. The most common type of logic-translator is the non-isolated bidirectional logic-level translator, which is used to translate logic signals from one voltage level to another. This type of translator is particularly useful for connecting systems that have different logic families.

NTB0101GW-Q100H Overview

The NTB0101GW-Q100H is a low-power bidirectional logic-level translator, designed to translate one voltage level to another while still maintaining signal integrity. The device is specifically designed to bridge logic families by converting signals from 2.5V to 3.3V or 3.3V to 2.5V. It is equipped with two channels and provides two independent translators, meaning two pairs of signals can be converted simultaneously. The NTB0101GW-Q100H operates at a low, 70 μA quiescent current, and is capable of providing a total of 400mA of current while operating at 2.5V or 3.3V.

NTB0101GW-Q100H Application Field and Working Principle

One of the major applications of logic translators such as the NTB0101GW-Q100H is to bridge logic families, allowing one system to communicate with another that has different signal voltages. The unit is ideal for bridging between an MCU with an I2C slave device, or for connecting to a 3.3V device from a 2.5V system.The NTB0101GW-Q100H operates on a Schmitt trigger circuit, which buffers the signal to quickly make a decision whether it is high or low. This allows the signal to be accurately maintained between two devices, without power related issues. The device has two channels and each channel is composed of two inputs, two outputs and one enable signal. The two input signals are connected to the microcontroller and the two output signals are connected to the I2C slave. The enable signal is used to enable the translator. When enabled, the unit will translate between the two logic families, converting the signal from 2.5V to 3.3V or 3.3V to 2.5V. The device then outputs the new signal on the other side, allowing the two systems to communicate.The NTB0101GW-Q100H is also designed to feature bidirectional voltage translation, meaning it can translate from one voltage to another in both directions. This allows it to be used as a bidirectional level shifter or even a bi-directional converter. A key feature of the device is to provide low-power operation; while it can provide up to 400mA of output current, the unit only requires 70 μA of quiescent current. This makes the device well-suited for applications with limited power requirements.The NTB0101GW-Q100H is an excellent choice for applications that require reliable logic conversion. It can quickly and accurately convert signals from one voltage to another, allowing different electronic systems to easily communicate. The device features low-power operation, bidirectional voltage translation, and is an ideal solution for applications with limited power requirements.
