Based on recommendations in the A1458 optocoupler datasheet and industry best practices: a1458 optocoupler datasheet
This datasheet is for informational purposes. Verify specifications with original component supplier before design-in.
The device is commonly found in an 8-pin DIP or SO-8 package. While you should always verify with the official datasheet, a standard high-speed optocoupler pinout follows this logic: The (also commonly referred to as the Go
The A1458 is not an ultra-high-speed device (like a logic gate optocoupler, e.g., 6N137), but it is adequate for most power supply feedback and low-speed data isolation (< 50 kHz).
Common Mode Transient Immunity (CMR): High noise immunity, typically 15 kV/µs to 50 kV/µs, essential for preventing false triggers in noisy industrial settings. Common Mode Transient Immunity (CMR): High noise immunity,
Based on standard optocoupler architecture (an infrared LED optically coupled to a phototransistor), the A1458 datasheet should prioritize these parameters:
