Frequently Asked Questions
How does PS9821-2-A support isolated digital communication links?
PS9821-2-A provides 2 channels with a 15 MBps nominal data rate, allowing two fast logic paths to cross an isolation barrier in control systems.
Which isolation requirement should designers compare against this optocoupler?
Designers should compare the 2500 V maximum isolation voltage against system safety spacing, transient exposure, and regulatory requirements before using the part in a high-voltage interface.
What package and drive details matter during schematic review?
Reviewers should check the 8 pins SO footprint, surface-mount assembly flow, and 0.015 A maximum forward current so the LED drive circuit is sized correctly.
