DATASHEET ISL33001, ISL33002, ISL33003 FN7560 Rev 6.00 I2C Bus Buffer with Rise Time Accelerators and Hot Swap Capability July 11, 2014 The ISL33001, ISL33002, ISL33003 are 2-Channel Bus Buffers Features that provide the buffering necessary to extend the bus 2 2 2 Channel I C compatible bi-directional buffer capacitance beyond the 400pF maximum specified by the I C specification. In addition, the ISL33001, ISL33002, ISL33003 +2.3VDC to +5.5VDC supply range feature rise time accelerator circuitry to reduce power >400kHz operation consumption from passive bus pull-up resistors and improve Bus capacitance buffering data-rate performance. All devices also include hot swap circuitry 2 to prevent corruption of the data and clock lines when I C devices Rise time accelerators are plugged into a live backplane, and the ISL33002 and Hot swapping capability ISL33003 add level translation for mixed supply voltage applications. The ISL33001, ISL33002, ISL33003 operate at 6kV Class 3 HBM ESD protection on all pins supply voltages from +2.3V to +5.5V at a temperature range of 12kV HBM ESD protection on SDA/SCL pins -40C to +85C.
