The —often listed in datasheets as the NTE1458 or referenced alongside similar industrial optoisolators—is a specialized electronic component designed to provide electrical isolation between two separate circuits. By transferring electrical signals using light waves, it prevents high voltages from damaging sensitive receiving components.

To fully leverage the high isolation capabilities of the 1458 optocoupler, strict adherence to PCB safety layout practices is required:

The HCPL-1458 series is frequently used in industrial and high-reliability sectors:

The is a high-performance, high-speed optocoupler optimized for low-voltage signal isolation. Manufactured by Broadcom (formerly Avago Technologies), this device features a GaAsP LED optically coupled to an integrated high-gain photodetector . It provides up to 3750 Vrms of electrical isolation to protect sensitive logic circuits from high-voltage spikes, eliminate ground loops, and minimize common-mode noise in demanding digital environments.
