1458 Optocoupler Datasheet Here

The 1458 optocoupler is a robust component essential for noise reduction and safety in circuit design. By understanding the datasheet parameters—specifically Forward Voltage, CTR, and Isolation Voltage—you can safely implement it in your designs to bridge the gap between low-power logic and high-power peripherals.

If your part is a classic 8-pin analog amplifier (not an optical isolator), it is a dual op-amp derived from the industry-standard mu cap A 741 STMicroelectronics MC1458 - STMicroelectronics 1458 optocoupler datasheet
