PCA9516APW

The PCA9516APW is a dual bidirectional I²C bus buffer designed to extend the I²C bus and improve signal integrity in applications where the distance between master and slave devices exceeds typical limits. It operates on a power supply voltage of 3.0V to 5.5V and supports standard I²C data rates up to 1 MHz.
This device is particularly useful in systems with multiple I²C devices, enabling the connection of devices with different supply voltages by isolating them. The PCA9516APW features two channels, allowing separate buffering for each I²C bus line (SDA and SCL), which helps minimize signal degradation.
Key features include low propagation delay, a wide voltage range, and support for both fast-mode and standard-mode I²C communication. It is available in a TSSOP-20 package, making it suitable for compact designs. Overall, the PCA9516APW is an effective solution for enhancing I²C communication in complex electronic systems.
