Overview
The PCA9600DP/S911,118, produced by NXP USA Inc., is a dual bidirectional bus buffer designed to isolate I²C-bus capacitance. This component enables the extension of I²C-bus lines in point-to-point or multipoint applications, supporting bus lengths with capacitance up to 4000 pF. It is a higher-speed version of the P82B96, capable of operating at speeds up to at least 1 MHz and compliant with Fast-mode Plus (Fm+) specifications. The PCA9600DP is suitable for interfacing with various bus configurations, including SMBus, PMBus, and microprocessors using TTL logic levels.
