Isoloop digital isolators
Want to lose those slow opto isolators and opto couplers? Try the IsoLoop
ten point plan for kicking the opto isolator habit.
 |
Active
input digital magnetic isolators
Single, dual, four
and five channel 150 Mbps active input Isoloop digital isolators. Ideal
for logic level shifting, isolated data interfaces, peripheral interfaces,
Profibus, DeviceNet, CANbus & I2C bus applications. |
 |
Isolated
bus transceivers
Isolated RS422, RS485
( with or without handshake ) and Profibus interfaces. Low cost and
fractional load transceivers. |
 |
Passive
input isolators
Single and dual input
and output Isoloop digital isolators, ideal for CANbus and I2C bus applications,
isolated gate drives and logic level shifting. Smallest versions available
in MSOP package. |
 |
DC
correct digital isolators
Compared to the industry
standard IL700-series, which have speeds up to 150 Mbps, IL500-Series
isolators are more cost effective, offer a DC-correct design, and have
an external clocking option on some models. |
