Texas Instruments PCA9515A Dual Bidirectional I2C Bus and SMBus Repeater PCA9515AD

The PCA9515A is a dual bidirectional I2C bus and SMBus repeater designed to extend the range and improve the performance of I2C systems. It features two-channel bidirectional buffers that are compatible with both I2C and SMBus protocols. The device operates within a voltage range of 2.3V to 3.6V and supports 5.5V tolerant I/O, making it versatile for various applications. This repeater enables the connection of two I2C buses, allowing for longer trace lengths and accommodating more devices by effectively managing the bus capacitance limit of 400pF. The PCA9515A includes an active-high enable input for controlling the repeater's operation, which helps isolate faulty devices during power-up or reset conditions. It is important to note that the device does not support clock stretching. The PCA9515A is suitable for applications requiring reliable communication in mixed-mode signal environments and is designed to prevent lockup conditions during operation. It is available in multiple package types, including SOIC and VSSOP, and operates within a temperature range of -40¬8C to 85¬8C.
