The PCA9512ADP,118 from NXP Semiconductors is a bidirectional buffer designed for I2C-bus and SMBus applications, enabling hot-swappable insertion and removal of I/O cards without data corruption.
This device provides level shifting capabilities between 3.3V and 5V systems, ensuring optimal noise margins. It operates within a supply voltage range of 2.7V to 5.5V and supports clock frequencies up to 400kHz. The buffer features built-in rise time accelerators on SDA and SCL lines, which can be disabled via an ACC pin for lightly loaded systems.
Key features include a 1V precharge on I/O pins during insertion to minimize current draw and isolation of backplane and card capacitances. The PCA9512ADP,118 is compatible with I2C-bus Standard mode, Fast mode, and SMBus standards.
Packaged in an 8-TSSOP, this buffer is suitable for surface mounting and is designed for applications requiring live board insertion and removal from multipoint backplane systems, such as cPCI, VME, and AdvancedTCA cards.
