I2C Bus Buffer with Rise Time Accelerators and
Hot Swap Capability
ISL33001, ISL33002, ISL33003
The ISL33001, ISL33002, ISL33003 are 2-Channel Bus
Buffers provide the necessary buffering for extending 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 level
translation for mixed supply voltage applications.
The ISL33001, ISL33002, ISL33003 operates at supply
voltages from +2.3V to +5.5V at a temperature range of
-40°C to +85°C.
