MCA231
MCA231 is Optically-Coupled Darlington Isolator manufactured by Fairchild Semiconductor.
- Part of the MCA230 comparator family.
- Part of the MCA230 comparator family.
Description
The MCA230, MCA231 and MCA255 series of optically-coupled isolators are electrical and mechanical replacements for the Monsanto series. Optical intercoupling provides a high degree of ac and dc isolation. Connection to the base is also provided for design flexibility.
