The BA664 is an IC with a built-in clamp diode, developed for the purpose of minimizing attachments, and contains a
Darlington transistor array of six circuits with input resistance. Input and output are directed in the same direction by
DIP Pin 14, with the layout optimized to facilitate mounting.
