Description
The PCA9511A is a hot swappable I2C-bus and SMBus buffer that allows I/O card insertion into a live backplane without corrupting the data and clock buses.
Features
- s Bidirectional buffer for SDA and SCL lines increases fan out and prevents SDA and SCL corruption during live board insertion and removal from multi-point backplane systems s Compatible with I2C-bus standard mode, I2C-bus fast mode, and SMBus standards s Built-in ∆V/∆t rise time accelerators on all SDA and SCL lines (0.6 V threshold) s Active HIGH ENABLE input s Active HIGH READY open-drain output s High-impedance SDA and SCL pins for VCC = 0 V s 1 V precharge on all SDA and SCL lines s Support.
