This guide consolidates key technical information, applications, and selection criteria to serve as a practical reference. For the final and most accurate design, always consult the official manufacturer's datasheet for your specific part number.
(Pin 6) and (Pin 4) to your isolated power supply. Note: Always place a small decoupling capacitor (e.g., ) close to the VCCcap V sub cap C cap C end-sub pin to filter out high-frequency noise. 1458 optocoupler datasheet
: Common high-speed optocouplers, although input current and speed specifications may vary, requiring a re-check of your resistor values. Note: Always place a small decoupling capacitor (e
The unique hermetic sealing and high-gain characteristics of the HCPL-1458 make it suitable for specialized environments: The voltage levels you need to isolate
Your targeted or switching frequency. The voltage levels you need to isolate.
Optimized for low-power and low-voltage systems, it features a wide VCCcap V sub cap C cap C end-sub range of 3.0V to 5.5V.
