ISL33002中文资料I2C Bus Buffer with Rise Time Accelerators and Hot Swap Capability数据手册Renesas规格书

描述 Description

The ISL33002 two-channel bus buffer provides the buffering necessary to extend the bus capacitance beyond the 400pF maximum specified by the I2C specification. In addition, the ISL33002 features rise time accelerator circuitry to reduce power consumption from passive bus pull-up resistors and improve data-rate performance. The device also includes hot-swap circuitry to prevent corruption of the data and clock lines when I2C devices are plugged into a live backplane, and the ISL33002 adds level translation for mixed supply voltage applications. The ISL33002 operates at supply voltages from +2.3V to +5.5V at a temperature range of -40 °C to +85 °C.
