General Schematic Notes
The following table lists summary information about notes appearing in schematic diagrams.
Table 6-4. General Schematic Notes
1.
All resistors are in ohms
±
1%, 1/8W, unless otherwise specified.
2.
All capacitors are in microfarads unless otherwise specified.
3.
Signal lines that are terminated by flags continue on other sheets, and may also go to other locations on the same sheet.
Example: CVPROG (SH.2 8C); "SH.2 8C" indicates the sheet number and the coordinates on that sheet where the
CVPROG signal line goes.
4.
Unterminated signal lines go to a least one other location on the same sheet.
5.
Unless otherwise noted, bias connections to integrated-circuit packages are as follows:
Common
+ 5V
14-pin packages
pin 7
pin 14
16-pin packages
pin 8
pin 16
20-pin packages
pin 10
pin 20
