Logic level shifting may be required when interfacing legacy devices with newer devices that use a smaller geometry process. For bidirectional bus systems like the I2C-bus, such a level shifter must ...
The first parallel-to-serial I2C interface lets designers add I2C interfaces to any digital system. The PCA9564 controller provides a 400-kHz I2C serial bus and operates from 2.5 to 3.3 V. The chip is ...
This dual bidirectional I2C and SMBus voltage-level translator, with an enable (EN) input, is operational from 1.2-V to 3.3-V VREF1 and 1.8-V to 5.5-V VREF2. The PCA9306 allows bidirectional voltage ...
