Note: $V_CEO$ varies significantly by manufacturer; always verify the specific brand.

The 1458 optocoupler, also known as the PC817 or 817 optocoupler, is a popular optoelectronic device used for electrical isolation and signal transfer between two circuits. This report provides an in-depth analysis of the 1458 optocoupler datasheet, highlighting its key features, specifications, and applications.

Unlike legacy high-speed optocouplers that require a rigid 5V supply, the HCPL-1458 thrives between . This makes it perfectly tailored for battery-powered systems, IoT nodes, and modern low-power microcontrollers operating on a 3.3V bus. High-Speed Propagation Low Delay 1458 optocoupler datasheet

The HCPL-1458 integrates a high-efficiency Gallium Arsenide Phosphide (GaAsP) Light Emitting Diode (LED) on the input side. This LED is optically coupled to an integrated, high-gain, high-speed photodetector chip on the output side.

Features a remarkably low propagation delay—typically around 35 ns at 10 kHz —enabling high-frequency data rates and precise signal timing. Unlike legacy high-speed optocouplers that require a rigid

If the user needs an optocoupler and mistakenly searched for "1458," here are correct alternatives:

): The open-collector output pin that pulls low when the input LED is active. This LED is optically coupled to an integrated,

The is a specialized, hermetically sealed, high-speed optocoupler designed to provide robust electrical isolation between low-voltage control circuits and high-voltage power components. Originally engineered by Avago Technologies (now Broadcom) and historically associated with Agilent, this component combines a gallium arsenide phosphide (GaAsP) Light Emitting Diode (LED) with an integrated, high-gain photodetector in an industry-standard package.

Functions as an isolated line receiver to process digital signals across long data lines traversing high-noise manufacturing floors. Equivalent Components and Replacements
