The (also referred to as the A1458 ) is a high-speed, logic-gate optocoupler primarily manufactured by Broadcom (formerly Avago/Agilent) . It is designed to provide high-speed signal isolation between a circuit's input and output, protecting sensitive low-voltage components from high-voltage transients. Key Technical Specifications
