Product details

Description

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.

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 speciﬁcation. The SDAx and SCLx pins are overvoltage tolerant and are high-impedance when the PCA9527 is unpowered. The port B drivers (SDAB, SCLB, CECB) with static level offset behave much like the drivers on the PCA9515 devi.
