I C Bus Buffer with Rise Time Accelerators and  
Hot Swap Capability  
ISL33001, ISL33002, ISL33003 Features  
2
• 2 Channel I C Compatible Bi-Directional Buffer  
• +2.3VDC to +5.5VDC Supply Range  
• >400kHz Operation  
The ISL33001, ISL33002, ISL33003 2-Channel Bus  
Buffers provide the necessary buffering for extending the  
bus capacitance beyond the 400pF maximum specified  
2
by the I C specification. In addition, the ISL33001,  
• Bus Capacitance Buffering  
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  
• Rise Time Accelerators  
• Hot-Swapping Capability  
• ±6kV Class 3 HBM ESD Protection On All Pins  
• ±12kV HBM ESD Protection on SDA/SCL Pins  
• Enable Pin (ISL33001 and ISL33003)  
• Logic Level Translation (ISL33002 and ISL33003)  
• READY Logic Pin (ISL33001)  
2
corruption of the data and clock lines when I C 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.  
• Accelerator Disable Pin (ISL33002)  
• Pb-Free (RoHS Compliant) 8 Ld SOIC (ISL33001  
only), 8 Ld TDFN (3mmx3mm) and 8 Ld MSOP  
packages
