Description
The STISO621 are dual-channel digital isolators based on the ST thick oxide
galvanic isolation technology.
The devices provide two independent channels in opposite direction with Schmitt
trigger input, providing robustness to noise and high speed input/output switching
time.

Application
• Optocoupler replacement in industrial application
• Industrial field bus isolation
• Battery monitor and motor drive
• Size-critical multichannel isolation
