For precise circuit integration, refer to these electrical characteristics typically found in the HCPL-1458 datasheet : Typical Value Max Rating Forward Voltage ( VFcap V sub cap F ) Output Current ( IOcap I sub cap O ) Supply Voltage ( VCCcap V sub cap C cap C end-sub ) Propagation Delay Isolation Voltage 1500 V – 3750 Vrms Depends on package Pinout Configuration
By understanding the structure of an optocoupler datasheet, you can confidently select the correct component for your power supply, microcontroller interface, or industrial control project—regardless of the mythical "1458." 1458 optocoupler datasheet
Isolating sensitive microcontrollers from high-voltage transients in Motor Drives . For precise circuit integration, refer to these electrical
The SOP-8 package is often hermetically sealed , protecting the internal components from environmental moisture and contaminants to ensure long-term reliability. Common Applications If you are looking for an optocoupler (opt
The classic is a dual operational amplifier (op-amp). If you are looking for an optocoupler (opt isolator) , common similar-looking numbers are:
F bypass capacitor is strictly recommended between Pins 5 and 8 to stabilize the high-speed detector.
When the 24V signal is HIGH, the LED turns on, the phototransistor conducts, pulling the microcontroller pin LOW (active low). When the signal is LOW, the phototransistor is off, and the pull-up resistor makes the microcontroller pin HIGH.
