DESCRIPTION
The ILCT6 is a two channel opto isolator for high density applications. Each channel consists of an optically coupled pair with a gallium arsenide infra- red LED and a silicon NPN phototransistor. Signal information, including a DC level, can be transmit- ted by the device while maintaining a high degree of electrical isolation between input and output. The ILCT6 is especially designed for driving medium-speed logic, where it may be used to elimi- nate troublesome ground loop and noise problems. It can also be used to replace relays and transform- ers in many digital interface applications, as well as analog applications such as CRT modulation.
