PCA9527 - 3-channel bidirectional bus extender
The PCA9527 is a 3-channel bidirectional open-drain bus buffer for Display Data Control (DDC) clock, data and Consumer Electronic Control (CEC) for HDMI application.
The device has two power supply pins to allow voltage level shift from 2.7 V to 5 V, and a rise time accelerator on port A of each DDC
PCA9527 Features
* of the I2C-bus system during the level shift, it also permits extension of the I2C-bus by providing bidirectional buffering for data (SDA), clock (SCL), and CEC. Using the PCA9527 enables the system designer to isolate bus capacitance to meet HDMI DDC version 1.3 distance speciļ¬cation. The SDAx and
