ISL33001, ISL33002, ISL33003
I2C Bus Buffer with Rise Time Accelerators and Hot Swap Capability
DATASHEET
The ISL33001, ISL33002, ISL33003 are 2-Channel Bus Buffers that provide the buffering necessary to extend the bus capacitance beyond the 400pF maximum specified by the I2C specification. In addition, the ISL33001, ISL33002, ISL33003 feature rise time accelerator circuitry to reduce power consumption from passive bus pull-up resistors and improve data-rate performance. All devices also include hot swap circuitry to prevent corruption of the data and clock lines when I2C devices are plugged into a live backplane, and the ISL33002 and ISL33003 add level translation for mixed supply voltage applications. The ISL33001, ISL33002, ISL33003 operate at supply voltages from +2.3V to +5.
