Texas Instruments PROTOTYPE PCA9515BDRGR

The PCA9515BDRGR is an I²C bus buffer/expander IC from NXP (formerly Philips Semiconductors), part of the PCA9515 series. It's a BiCMOS device designed to isolate and extend I²C buses by providing two independently controllable bidirectional channels. This particular package type, DRGR, likely refers to a specific surface-mount package such as SOIC or TSSOP, suitable for reflow soldering onto printed circuit boards. The component enables communication between separate I²C segments while protecting each segment from bus contention and overloading.
