NOTE: Transistors and integrated circuits are marked for identification in
one of the following four ways:
1. Part number.
2. Type number. (For integrated circuits this refers only to the
numbers, the letters may vary.)
3. Part number and type number.
4, Part number with a type number other than the one listed.
