Product Description

The PCA9515ADP from NXP is a dual-channel I2C Repeater and I2C Level Shifter IC designed to buffer and extend I2C bus communication. It supports bidirectional voltage translation between I2C devices operating at 1.8V, 3.3V, or 5V logic levels, enabling seamless interfacing across mixed-voltage systems. The device features two active-high enable pins, allowing independent control of two bidirectional channels. With a wide operating voltage range of 2.3V to 5.5V and temperature support from -40°C to +85°C, it suits industrial automation, telecom, and embedded systems. Key advantages include low standby current, hot-swap protection, and compatibility with 400kHz Fast-mode I2C. A limitation is reduced maximum node count due to bus capacitance constraints. As a bus buffer, it eliminates signal integrity issues in multi-drop or long-distance I2C networks.
