The TXB0302DQMR is an isolated level shifter, which translates logic levels between high voltage and low voltage applications. It has been designed for operation over a wide range of supply and logic levels. While there are similar devices on the market, what sets this one apart is the built-in transceiver that can support very long run lengths (up to 10 meters) between two units.
Overview
The TXB0302DQMR is an integrated electrical isolation, bidirectional level translator with two primary functions:
- First, it boosts the logic level in one direction and boosts logic level in the opposite direction by providing an adjustable voltage divider in between.
- Second, it supports “5-V tolerant” operation on the lower side of the level-shifting function by providing protection circuitry that eliminates the need for costly external voltage-translation components.
It is programmable from 0-V to 12-V (or any intermediate value) in both directions with just two resistor values. On the input side, the device can accept 5- or 3-V logic levels without any additional components. On the output side, the level shifter can be configured for output voltages between 0-V and 12-V. This device supports I2C, SPI and synchronous serial communications.
Operation
The TXB0302DQMR level shifter is a bi-directional device, meaning it can both boost and translate logic levels in either direction. When the input voltage supply is higher than the output voltage supply, the device will boost the logic level to the higher voltage. When the input voltage supply is lower than the output voltage supply, the device will boost the logic level to the lower voltage.
The device features adjustable voltage dividers on the input and output sides of the level-shifting circuit. When the input voltage is higher than the output voltage, the device will boost the input signal when the adjustable voltage divider is set to the higher voltage. When the input voltage is lower than the output voltage, the device will attenuate the input signal when the adjustable voltage divider is set to the lower voltage.
The TXB0302DQMR level shifter also features integrated protection circuitry, which allows the device to work with input voltages as low as 0-V on the input side and output voltages as low as 0-V on the output side.
Applications
The TXB0302DQMR level shifter is ideal for applications where there is a need to interface between disparate logic families, such as consumer electronics and industrial control systems, or between different communication protocols, such as I2C, SPI and synchronous serial communication. It can also be used in automotive and medical applications, as well as in digital audio applications such as CD players and digital amplifiers.
The adjustable voltage dividers on both the input and output sides make the device ideal for translating between different voltage supplies. The integrated protection circuitry allows the device to be used in applications with low voltage supplies or high voltage spikes. The integrated transceiver also makes the device suitable for applications requiring very long run lengths, up to 10 meters between two units.
Conclusion
The TXB0302DQMR level shifter is an innovative device, designed to bridge the gap between disparate logic families and communication protocols, as well as between different voltage supplies. The integrated transceiver and adjustable voltage dividers make it a perfect solution for even the most challenging applications. Its versatility and ease of use make the device a great option for anyone looking for a reliable, cost-effective level-shifting solution.
