1458 Optocoupler Datasheet !!top!! Jun 2026

Your targeted or switching frequency. The voltage levels you need to isolate.

The following appendix provides additional information on the 1458 optocoupler datasheet:

: High-speed logic ground isolation (TTL/CMOS compatible).

: Commonly available in a compact SOP-8 or SOIC package style. Pin Configuration (Standard SOP-8) While pinouts can vary by manufacturer, the typically follows this configuration: Input Pins : Dedicated to the LED power supply and ground. 1458 optocoupler datasheet

Collector terminal of the Channel 1 phototransistor.

Note: Switching speeds are highly dependent on the load resistance ( RLcap R sub cap L ) tied to the collector. 5. Understanding the Current Transfer Ratio (CTR)

In power electronics, such as solar inverters and industrial motor drives, the alternative variant HCPL-A1458 is frequently deployed as a gate driver helper. It safely conveys switching logic from low-voltage controllers to high-voltage IGBT or MOSFET stages. Vital Design and Layout Guidelines Your targeted or switching frequency
