PCA9522 Overview
Key Specifications
Package: SOP
Pins: 8
Operating Voltage: 3.3 V
Max Voltage (typical range): 5.5 V
Description
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.
Key Features
- Dual, bidirectional unity gain isolating buffer
- Hot insertion logic prevents data and clock bus corruption for live backplane
