A1458 Optocoupler Datasheet Patched

Keep in mind that infrared LEDs lose efficiency (diminish in light output) over decades of continuous use. Design your initial circuit with enough "CTR Margin" (e.g., planning for 50% of the rated CTR) to ensure longevity.

The A1458 is typically housed in a space-saving or a standard 8-pin Dual In-line Package (DIP-8) .

Provides mechanical drawings of the DIP-8 or SOP-8 package, including dimensions for PCB footprint creation (land pattern). Share public link This is the heart of the datasheet

What (e.g., relay, sensor, data bus) are you driving on the output side?

When two systems operate on separate grounds (e.g., analog grounding vs. noisy digital motor grounding), connecting them directly can introduce ground loops and electrical interference. The A1458 isolates the two ground potentials perfectly. IV. Telecommunications Equipment

Available in standard surface-mount (SMD) and dual-in-line (DIP) packaging for versatile PCB design.
