DESCRIPTION
The IL201/202/203 are optically coupled pairs
employing a Gallium Arsenide infrared LED and a
Silicon NPN phototransistor. Signal information,
including a DC level, can be transmitted by the
device while maintaining a high degree of electrical
isolation between input and output. The IL201/202/
203 can be used to replace relays and transformers
in many digital interface applications, as well as
analog applications such as CRT modulation.
