A1458 Optocoupler Datasheet !exclusive! Official

Understanding the pinout is crucial for proper circuit integration. While the pinout can vary slightly based on the specific variant (PDIP-8 vs. SOIC-8), the A1458 family generally follows a standard configuration.

Most DIP-4 optocouplers follow a standard pinout. The A1458 likely adheres to this:

Extremely high common mode transient immunity (CMTI) ensures reliable performance in "noisy" industrial environments.
