ISL33002

I2 C Bus Buffer with Rise Time Accelerators and Hot Swap Capability

Product Status: 量産中

OVERVIEW

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 I2 C 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 I2 C 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 +5.5V at a temperature range of -40°C to +85°C.
