The PCA9511ADP,118 is a hot-swappable I2C-bus and SMBus buffer designed by NXP Semiconductors. This component allows for I/O card insertion into a live backplane without corrupting data and clock buses. It provides bidirectional buffering, isolating backplane and card capacitances.
Key features include a rise time accelerator circuitry for improved performance with weaker pull-up currents and a 1V precharge on SDA and SCL lines to minimize charging current for parasitic capacitance. The device operates over a supply voltage range of 2.7V to 5.5V and supports clock frequencies from 0 Hz up to 400 kHz.
It is compatible with I2C-bus Standard-mode, Fast-mode, and SMBus standards. The PCA9511ADP,118 includes an active HIGH ENABLE input and an active HIGH READY open-drain output. ESD protection exceeds 2000V HBM.
This buffer is available in an 8-TSSOP package and is suitable for surface mount applications. It is designed for multipoint backplane systems like cPCI, VME, and AdvancedTCA cards that require insertion or removal from an operating system.
