Mikroelektronika MIKROE-3276 Port Expander I2C Logic Level Converter 1.2V to 10V

Technical description of the product (MIKROE-3276):

MIKROE-3276 Port expander, voltage level conversion in the range from 1.2V up to 10V. LLC I2C click can be utilized as the level converter for logic signals, which makes it a very useful Click board™. The topology of this logic level conversion (LLC) circuit is perfectly suited for the bi-directional I2C communication. Although there are some specialized integrated circuits on the market, sometimes it is more convenient to have a simple solution made of just a few passive elements and four MOSFETs. Besides this, MOSFETs can withstand up to 20V across their terminals (12V VGS), and they support far greater currents than typical ICs, making them less likely to fail. The LLC circuitry, also known as the level translator or level shifter, can be used in virtually any application that utilizes the I2C communication protocol and needs matching between the logic voltage levels. Type: Port expander. Applications: The I2C logic level conversion circuit has its application in many different projects, for the logic voltage level matching between the I2C master, and the I2C slave device. Key Features: Very low cost achieved using only passive elements, and four MOSFETs, ability to use an arbitrary voltage level conversion in the range from 1.2V up to 10V. Interface: I2C. Input Voltage: 3.3V or 5V. Click board size: M (42.9 x 25.4 mm).
