The PCA9511AD,112 from NXP Semiconductors is a bidirectional buffer designed for I2C-bus and SMBus applications. It facilitates hot-swapping of I/O cards into live backplanes without corrupting data or clock buses. The device provides bidirectional buffering, isolating backplane and card capacitances.
Key features include a 2.7V to 5.5V operating supply voltage range and a maximum clock frequency of 400kHz. It incorporates rise time accelerators for improved performance with weaker pull-up currents. The buffer has an active HIGH ENABLE input and an open-drain READY output. It supports clock stretching and multiple master arbitration.
This buffer is suitable for applications requiring live insertion and removal from multipoint backplane systems, such as cPCI, VME, and AdvancedTCA cards. The PCA9511AD,112 is available in an 8-SOIC package and is designed for surface mounting.
ESD protection exceeds 2000V HBM, 200V MM, and 1000V CDM. Latch-up testing exceeds 100 mA per JESD78.
