The PCA9514ADP,118 is an I2C-bus and SMBus buffer designed by NXP Semiconductors that allows for hot-swappable I/O card insertion into live backplanes without corrupting data and clock buses. It features bidirectional buffering for SDA and SCL lines, which increases fan-out and prevents corruption during live board insertion and removal from multipoint backplane systems.
This device operates over a voltage range of 2.7V to 5.5V and supports I2C-bus Standard mode, I2C-bus Fast mode, and SMBus standards up to a clock frequency of 400kHz. It incorporates built-in delta-V/delta-t rise time accelerators with a 0.8V threshold for improved noise margin. The PCA9514ADP,118 includes an active HIGH ENABLE input and an open-drain READY output.
Packaged in an 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) format, this buffer is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C. The device has a capacitance of 1.9 pF and a current consumption of 3.5mA. The PCA9513A variant, noted in the datasheet, includes a 92 μA current source on SCLIN and SDAIN pins for specific backplane applications.
Key features include compatibility with I2C-bus and SMBus standards, rise time accelerators, and support for clock stretching, multiple master arbitration, and synchronization. The PCA9514ADP,118 is designed to isolate backplane and card capacitances, ensuring reliable communication in complex systems.
