PCA9614DPZ

The PCA9614DPZ is a dual bidirectional I²C bus buffer designed to extend the range and improve the reliability of I²C communications. It operates at high speeds, supporting standard I²C frequencies up to 1 MHz, and is particularly useful in applications where long distances between devices can lead to signal degradation.
This device features two channels, allowing for simultaneous buffering of two I²C buses. The PCA9614DPZ is capable of level shifting, enabling communication between devices operating at different voltage levels, typically 1.8V to 5.5V.
The buffer enhances signal integrity by reducing capacitance on the bus and enabling faster rise times. It also includes built-in pull-up resistors and features a fault-tolerant design, ensuring that if one side fails, the other can continue functioning.
Applications include telecommunications, industrial automation, and embedded systems where reliable data transfer is crucial. The PCA9614DPZ is available in various package types, making it versatile for different circuit designs.

The PCA9614DPZ is a high-speed, bi-directional I²C bus buffer designed to extend the I²C bus capacitance and increase communication distances. Key features include:
