: Available in an 8-pin hermetically sealed package (SOP-8 or similar), protecting internal components from environmental factors. Electrical Specifications Typical/Max Value Forward Current ( IFcap I sub cap F ) 20 mA (Max) Output Current ( ICcap I sub cap C ) Operating Temperature -55°C to +100°C Propagation Delay 35 ns at 10 kHz Common Applications
: Providing safe isolation between low-voltage control signals and high-voltage power stages like IGBTs and MOSFETs Switching Power Supplies : Used in feedback loops to maintain isolation. Manufacturer Resources For full technical details, you can refer to the official HCPL-1458 Datasheet
Typically available in SOP-8 (SOIC) or 8-pin DIP packages. RoHS Compliant: Compliant with environmental standards. 2. HCPL-1458 Pinout and Schematic
Pin 1: Anode Pin 2: Cathode Pin 3: No connection (NC) Pin 4: Emitter Pin 5: Collector Pin 6: Base (optional; leave open for standard operation)
The efficiency of the internal GaAs LED drops as operating temperatures rise. To counteract this, always design your circuit with extra margin (overdrive) for the input current.
A standard optocoupler datasheet is divided into eight critical sections. Here is what you need to look for.
The 1458 is a specific type of optocoupler, commonly used for isolating digital signals. Here's a general outline of what you might find in its datasheet:
