MAX22291EASA/V+T

Digital Isolators Overview

The MAX22291EASA/V+T is a reinforced, low-power, two-channel digital isolator utilizing capacitive coupling technology. It supports data rates up to 25 Mbps with a typical common-mode transient immunity of 50 kV/µs. The device operates on a supply voltage range of 1.71 V to 5.5 V and provides 3000 Vrms isolation voltage. It features unidirectional channel configuration with one input and one output per channel, packaged in an 8-SOIC format.

Digital Isolators Feature Summary

• Provides reinforced electrical isolation between circuits using high-reliability capacitive coupling architecture.
• Delivers fast signal transmission capabilities supporting data rates up to 25 Mbps for efficient communication.
• Ensures robust noise rejection against rapid voltage changes with high common-mode transient immunity.
• Operates across a wide single-supply voltage range compatible with various logic families.

Digital Isolators Applications

• CAN bus interface isolation
• RS-232 communication line protection
• RS-485 differential bus isolation
• SPI peripheral interface separation

Digital Isolators Procurement Notes

Verify the specific suffix designation to confirm the exact packaging configuration and reel specifications required for your assembly process. Confirm that the 8-SOIC package dimensions align with your PCB footprint constraints. Ensure the operating voltage requirements match your system's power rails before finalizing the component selection.

Digital Isolators Selection Notes

Select this component when reinforced isolation is mandatory for safety compliance rather than basic functional isolation. Consider the 25 Mbps speed limit for high-frequency applications. Evaluate the 3000 Vrms rating against your system's isolation voltage requirements. Check the unidirectional nature of the channels to ensure it fits your signal flow direction needs.
