The TLP721 is a high-performance optocoupler (photo-isolator) designed to provide electrical isolation between input and output circuits. It consists of a GaAs infrared LED and an NPN silicon phototransistor housed in a compact DIP-4 package. Ideal for signal isolation, switching, and interfacing between high and low voltage systems.
