General Purpose, Buffer/Bus Extender
Internal Switch(s)
Yes
Voltage - Supply
2.3 V ~ 5.5 V
Operating Temperature
-40°C ~ 85°C
Mounting Type
Surface Mount
Package / Case
8-TSSOP, 8-MSOP (0.118", 3.00mm Width)
For Use With
ISL33002MSOPEVAL1Z - EVAL BOARD ISL33002 8MSOP
Lead Free Status / RoHS Status

I
Hot Swap Capability
ISL33001, ISL33002, ISL33003
The ISL33001, ISL33002, ISL33003 2-Channel Bus
Buffers provide the necessary buffering for extending the
bus capacitance beyond the 400pF maximum specified
by the I
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 I
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.
