IL500-Series DC-Correct Digital Isolators
Internally-clocked digital isolators...

Internal clocking ensures deterministic power-up, and outputs always follow the outputs (“DC correct”). In some versions the clock can be disabled for ultra-low power consumption. IL500-Series Isolators are a cost-effective alternative to digital optocouplers in a number of applications including serial interfacesisolated Serial Peripheral Interface (SPI)isolated A/D converters, and isolated power interfaces

Key features are:

DC Correct
2 Mbps
10 ns PWD
1, 2, 3, or 4 Channels

Low EM Emissions
30 kV/µs min. Transient Immunity
44000 Year Barrier Life
MSOP and SOIC Packages
