Description
The ILD3/ ILQ3 are optically coupled isolated pairs
employing GaAs infrared LEDs and silicon NPN pho-
totransistors. 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 ILD3/ ILQ3 are especially designed for
driving medium-speed logic and can be used to elim-
inate troublesome ground loop and noise problems.
Also these couplers can be used to replace relays and
transformers in many digital interface applications
such as CTR modulation. The ILD3 has two isolated
channels in a single DIP package and the ILQ3 has
four isolated channels per package.
