package. While you should always verify with the official diagram from Broadcom's technical data

The A1458 typically comes in an or SO-8 (SOP-8) surface-mount package. The standard 8-pin logic-gate optocoupler pinout is as follows: Pin 1: No Connection (NC) Pin 2: Anode (Input LED) Pin 3: Cathode (Input LED) Pin 4: No Connection (NC) Pin 5: Ground ( GNDcap G cap N cap D Pin 6: VOUTcap V sub cap O cap U cap T end-sub (Output Signal) Pin 7: VEcap V sub cap E (Enable Pin, sometimes used for logic control) Pin 8: VCCcap V sub cap C cap C end-sub (Supply Voltage) Key Features & Advantages a1458 optocoupler datasheet
