A1458 Optocoupler Datasheet ((exclusive))

(often referred to by its full part number HCPL-A1458 ) is a high-speed logic gate optocoupler manufactured by Broadcom (formerly Avago/Agilent). Designed for high-performance industrial and digital logic isolation, it is frequently used to protect low-voltage microprocessors from high-voltage transients in electrically "noisy" environments. 1. Key Technical Specifications

Industrial Power: Used in solar and wind turbine inverters, motor drive inverters, and Variable Frequency Drives (VFDs).

Because of its high speed and robust isolation, the A1458 is a staple in several critical industries: Optocouplers and Opto-Isolators - Broadcom Inc. a1458 optocoupler datasheet

Schematic Walkthrough:

: 3750 Vrms to 5000 Vrms (depending on the specific package and testing standard). Environmental Operating Temperature : Ranges from -40°C to +85°C. Pinout and Package The A1458 is typically housed in an 8-pin SOP (Small Outline Package) DIP-8 package Input Side (often referred to by its full part number

The device is commonly found in an 8-pin DIP or SO-8 package. While you should always verify with the official datasheet, a standard high-speed optocoupler pinout follows this logic:

• If 4 pins, it is almost certainly a PC1458 (or equivalent like PC817).
• If 6 pins, look towards the 4N35 or H11A1.

) is a high-speed, logic-gate optocoupler designed by Broadcom (formerly Avago Technologies). It is specifically engineered for applications requiring robust galvanic isolation and high-speed signal transmission, such as industrial control systems and data communications. Core Specifications
