Overview
The PCA9515ADP/DG,118 is a CMOS integrated circuit designed by NXP USA Inc. for use in I²C-bus and SMBus systems. This component is specifically tailored to extend the capabilities of I²C-bus systems by buffering both the data (SDA) and clock (SCL) lines. This allows for the isolation of two halves of a bus, enabling more devices or longer bus lengths to be accommodated. It supports dual voltage operation, such as 5 V and 3.3 V, and can handle different bus speeds like 400 kHz and 100 kHz.
