Description:
Optically coupled infrared emitting diodes and phototransistors in dual-in-line packages. Single type is in a 6-pin DIL package, dual type is in an 8-pin DIL package and quad type is in a 16-pin DIL package. 
On the single type, a base lead is provided so that the device may be biased in the conventional manner.
