PCA9521
Overview
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.
- Features and benefits
- Dual, bidirectional unity gain buffer
- Fast switching times allow operation in excess of 1 MHz
- Supports I2C-bus (Standard-mode and Fast-mode), SMBus (standard and high power mode), PMBus and IPMB
- Enable allows bus segments to be disconnected
- Low standby current when not enabled
