DIAGRAMS AND CIRCUIT BOARD ILLUSTRATIONS
Symbols and Reference Designators
Graphic symbols for electrical and logic symbols, used on the diagrams, are based on ANSI Y32 .2, 1970, and ANSI
Y32 .14, 1973, "American National Standards Institute ." Logic symbols depict the logic function of the device in positive
logic . Copies of these standards can be obtained from the Institute of Electrical and Electronics Engineers, 345 East 47th
Street, New York, N .Y ., 11017. Exceptions and additions are shown on this sample diagram . These conform or are based on
the manufacturers data sheet and industry trends .
Resistor values are in ohms, unless noted otherwise, and the S2 symbol is omitted . Capacitor values >1 (e .g . 10) are in
picofarads (pF) and values <1 (e .g . 0.01) are in microfarads unless otherwise noted.
