1458 Optocoupler Datasheet Fixed -

Designed for high-voltage galvanic isolation barriers to prevent ground loops. Core Functionality Like most optocouplers, the consists of two primary internal components: Input Side:

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
