The TXS0102DQMR is a Bi-Directional, 1-Bit Level Shifter and Translator from the TXS010X family from Texas Instruments that is an advanced I/O solution for translating signals from one voltage domain to another. This device provides a high-performance solution for translating a single signal from logic level low-voltage devices to high-performance systems. It also ensures signal integrity and reliable communications when used in a variety of application scenarios, such as interfacing analog circuits and digital buses between different voltage supplies. The TXS0102DQMR allows both asynchronous and synchronous communications and is designed to accommodate a wide operating voltage range (1.1 V to 3.6 V).

The TXS010X family is specifically designed to support a wide range of logic levels and provide a robust signal-level shifting solution. The TXS0102DQMR is an integrated circuit with two SC (Single-Call) or DB (Double-Call) input and two SC or DB output pins. These two input pins allow the device to shift the logic level of the input signal from one voltage domain to another. The two output pins provide the shifted level output from the input signal. This device is capable of bi-directional translation between the two supply voltages and can be used for both synchronous and asynchronous signals.

The TXS0102DQMR has a wide range of applications in signal-level shifting, logic-level translation for interfacing logic circuits, voltage sensors, communications, audio/video electronics, low-power microcontrollers and other electronic components requiring a reliable signal-level translation from one voltage domain to another. It is also well suited for applications in digital power management solutions and power management solutions that require translation between high and low voltage domains.The device is designed to work within the 1.1 V to 3.6 V voltage range and requires minimal shutdown current (I_off = 3 µA). It features a high-switching speed of 4 ns (typical) to enable fast signal transmission and can be used in a variety of system architectures, including microcontroller-based systems and hardwired systems. The device is usually placed between two voltage domains and its operation can be characterized in two ways: First, it may be configured as a translator between two different logic levels, providing bidirectional signal-level translation. Second, it may be operated as a level shifter, translating signal levels from one domain to the other with no loss of resolution.

The working principle of the TXS0102DQMR is based on the concept of controlled resistance. This device is essentially a re-programmable resistor, wherein its resistance is automatically regulated depending upon the input signal levels. The internal resistance of the device is adjusted so that when the input signal levels are between 1.1 V and 3.6 V, the output signal levels will be held to the corresponding logic levels. The device is designed to sense the logic levels of the two voltage domains and automatically adjust its resistance accordingly. This allows the device to provide smooth and precise signal-level shifting between 2.5 V and 3.3 V with no loss of resolution.

In summary, the TXS0102DQMR is a highly versatile and reliable level shifter and translator with a wide range of applications. It can be used in a variety of system architectures, including microcontroller-based systems and hardwired systems, to provide bi-directional signal-level translation between two voltage domains. It features a wide operating voltage range, fast switching speed and low power consumption, making it a very useful device for signal-level translation applications. It also ensures signal integrity and reliable communication between the two voltage domains and can be used for both async and sync communications. By utilizing its re-programmable resistor technology, the device can be used to provide smooth, accurate and precise signal-level translation with no loss of resolution.
