: Often used as direct logic-output substitutes .
The HCPL-1458 is designed for high-performance signal isolation in demanding environments. a1458 optocoupler datasheet
): Often rated up to 35V or 70V depending on the specific variant. Usually ranges between 50mA and 100mA. Saturation Voltage ( : Often used as direct logic-output substitutes
, ensuring signal integrity in electrically noisy environments. Output Type Open Collector , allowing for flexible logic level shifting. Core Features & Design Hermetic Sealing Usually ranges between 50mA and 100mA
A good A1458 datasheet will show three standard applications:
Usually Pins 2 (Anode) and 3 (Cathode) for the GaAsP LED. Output Side: Pins 5 (GND), 6 ( VOUTcap V sub cap O cap U cap T end-sub ), and 8 ( VCCcap V sub cap C cap C end-sub
– Provide package type (DIP-4, DIP-6, SOIC-8), number of pins, isolation voltage, or application (motor drive, power supply, IGBT driver). I can then suggest a modern equivalent or typical pinout/specs.
