PCA9525 Datasheet (NXP Semiconductors) - Simple 2-wire bus buffer

PCA9525, Simple 2-wire bus buffer

The PCA9525 is a monolithic CMOS integrated circuit for bus buffering in applications including I2C-bus, SMBus, DDC, PMBus, and other systems based on similar principles.

The buffer extends the bus load limit by buffering both the SCL and SDA lines, allowing the maximum permissible bus capacitance o
