DESCRIPTION
Isolation Resistance

The ILD/Q1/2/5 are optically coupled isolated pairs employing GaAs infrared
LEDs and silicon NPN phototransistor. Signal information, including a DC
level, can be transmitted by the drive while maintaining a high degree of
electrical isolation between input and output. The ILD/Q1/2/5 are especially
designed for driving medium-speed logic and can be used to eliminate trou-
blesome ground loop and noise problems. Also these couplers can be
used to replace relays and transformers in many digital interface applica-
tions such as CRT modulation. The ILD1/2/5 has two isolated channels in a
single DIP package and the ILQ1/2/5 has four isolated channels per pack-
age.
