1458 Optocoupler Datasheet Jun 2026

The datasheet will usually include information on the package type, pin configuration, and dimensions.

The opening of any datasheet introduces the device's key selling points. For the HCPL-1458 series, these features set the stage for its performance. The is a high-speed, dual-channel optocoupler , meaning it houses two independent isolators in a single chip, which is great for saving space on a printed circuit board (PCB) and reducing overall component count. Similarly, the HCPL-1458 is designed for high-speed digital communication and provides electrical isolation to protect circuitry from electrical noise, ground loops, and interference.

Based on the HCPL-1458 datasheet , the device operates optimally within these parameters: VCCcap V sub cap C cap C end-sub 3.0 to 5.5 Input Current IFcap I sub cap F Propagation Delay tPLHt sub cap P cap L cap H end-sub tPHLt sub cap P cap H cap L end-sub Common Mode Immunity CMRcap C cap M cap R Isolation Voltage VISOcap V sub cap I cap S cap O end-sub Vrmscap V sub r m s end-sub Output Current IOcap I sub cap O Key Performance Drivers Low Power Consumption: With an ICCcap I sub cap C cap C end-sub

Found in the high-frequency switching stages of solar inverters, wind power systems, and uninterruptible power supplies (UPS). 1458 optocoupler datasheet

Trade-off: This bleeds off some of the optically generated base current, which decreases the overall CTR (sensitivity) but significantly increases the switching speed for PWM applications. 7. Troubleshooting and Best Practices

If you need help identifying a specific manufacturer for the

) is a high-performance, hermetically sealed optocoupler designed for high-speed digital isolation in demanding environments. High-speed logic gate optocoupler. Key Specs: Speed: Typically 10 MBd (megabaud). The datasheet will usually include information on the

or 8-pin widebody package, ensuring long-term reliability in harsh environments. Isolation:

The 1458 series optocouplers are typically housed in an 8-pin package. While the pinout can vary slightly depending on whether it's a single, dual-channel, or gate driver version, a common configuration for the single-channel logic output variant (like the HCPL-1458) is as follows:

Provides a high insulation voltage of 5000 Vrms (or 3750 Vrms for certain packages like the standard 8-pin DIP). The is a high-speed, dual-channel optocoupler , meaning
