ISL33003

The ISL33003 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 ISL33003 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 ISL33003 adds level translation for mixed supply voltage applications. The ISL33003 operates at supply voltages from +2.3V to +5.5V at a temperature range of -40 °C to +85 °C.
