ISOCOM 4 Channel Optocoupler, Darlington Output, DIP, 50mA, 5.3kV
ISOCOM 4-channel Darlington optocoupler with 5.3kV isolation & 500% CTR. Ideal for industrial, computing & signal processing applications.
The ISOCOM TIL199 is a high-density, four-channel optically coupled isolator, engineered to provide reliable signal isolation in sensitive electronic circuits. It integrates an infrared LED with an NPN silicon phototransistor in a single, compact package, ensuring efficient optical coupling and excellent noise immunity. This device is rigorously tested to guarantee a minimum Current Transfer Ratio (CTR) of 500%, making it highly responsive and suitable for applications demanding precise signal transmission with minimal loss.
Designed for through-hole mounting in a standard Dual In-line Package (DIP), the optocoupler offers robust electrical isolation up to 5.3kV, protecting low-voltage control circuits from high-voltage noise and transients. With a maximum forward current of 50mA and a collector-emitter voltage of 35V, it provides the necessary drive capability for a wide range of interfacing tasks. Its 16-pin configuration supports four independent isolation channels, saving valuable board space in multi-channel designs.
