to protect internal components from moisture and environmental contaminants. 2. Pin Configuration (SOP-8) While you should always verify with a specific manufacturer's PDF

The 1458 optocoupler datasheet provides a wealth of information that can be used to design and develop applications that utilize this device. Here are some tips on how to use the datasheet:

Working with optocouplers requires careful circuit layout and attention to detail. To get the most out of the HCPL-1458, keep these best practices in mind: 1458 optocoupler datasheet

If this works, your "1458 optocoupler" behaves exactly like a 4N35.

range of , allowing compatibility with both legacy 5V and modern 3.3V logic systems.

: Due to its hermetically sealed package, it is often selected for environments where moisture or contaminants would degrade standard plastic packages. Distinguishing the 1458 Family | If you need

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.

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. To get the most out of the HCPL-1458,

The is a high-performance part. However, because components occasionally go out of production or face supply constraints, designers sometimes need alternatives.

The HCPL-1458 is a high-speed, high-gain optocoupler manufactured by Broadcom (formerly Avago/Agilent). It is designed for applications requiring high reliability in harsh environments, often featuring a hermetically sealed SOP-8 package. Key Features & Specifications
