Overview

PCA9521 Fast dual bidirectional bus buffer Rev.
2 — 19 March 2013 Product data sheet 1.
General description The PCA9521 is a monolithic bipolar integrated circuit for bus buffering in applications including I2C-bus, SMBus, PMBus, and other systems based on similar principles.
The buffer extends the bus load limit by buffering both the SCL and SDA lines.
It supports up to 400 pF loads on each side of the buffer at 400 kHz.
Higher capacitance is supported at lower speeds, and lower capacitance at higher speeds up to 1 MHz.
The enable function allows sections of the bus to be isolated.
Individual parts of the system can be brought on-line successively.
This means a controlled start-up using a...
