Always download the latest official datasheet from a verified distributor (Mouser, DigiKey, or the manufacturer’s site) before finalizing your design. The information provided here is a comprehensive guide, but nothing replaces the manufacturer’s certified data.

If the exact A1458 model is unavailable, the following alternatives can be considered, but verify pin-to-pin compatibility via their respective datasheets:

Very low, often rated at approximately 35 ns to 45 ns , making it suitable for high-speed digital data rates up to 15 Mbps . Isolation Voltage ( Visocap V sub i s o end-sub Supply Voltage ( VCCcap V sub cap C

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

Today, we are taking a deep dive into the datasheet of a specific workhorse in the industry: the . While often overshadowed by its famous cousin, the PC817, the A1458 holds its own as a reliable component for signal transmission and isolation.
