PCA9522 Overview
PCA9522 Fast dual bidirectional bus buffer with hot insertion logic Rev. 1 — 28 September 2011 Product data sheet 1. General The PCA9522 is a monolithic bipolar integrated circuit for bus buffering in applications including I2C-bus, SMBus, etc. It includes hot insertion logic for detecting stop and idle conditions, making it ideal for live insertion into backplanes. The buffer extends the bus load limit by buffering both the SCL and SDA lines....
PCA9522 Key Features
- Dual, bidirectional unity gain isolating buffer
- Hot insertion logic prevents data and clock bus corruption for live backplane
