ISL3300x I2C Bus Buffers

Renesas Electronics ISL3300x I²C Bus Buffer with Rise Time Accelerators provides the buffering necessary to extend the bus capacitance beyond the 400pF maximum specified by the I²C specification. Renesas ISL3300x Buffers feature rise time accelerator circuitry to reduce power consumption from passive bus pull-up resistors and improve data-rate performance. The devices also include hot-swap circuitry to prevent corruption of the data and clock lines when I²C devices are plugged into a live backplane. The ISL33002 and ISL33003 add a level translation for mixed supply voltage applications. The ISL3300x I²C Bus Buffers operate at supply voltages from +2.3V to +5.5V at a temperature range of -40°C to +85°C.
