IEEE 91-1984 pdf free.IEEE Standard Graphic Symbols for Logic Functions.
IEEE 91 comprises an outline or combination of outlines together with one or more qualifying symbols. Applicationof the symbols requires, in addition, the representation of input and output lines.
Symbols often make use of internal labels. It is essential to maintain clarity between internal labels that apply to signallines and internal labels that serve as general qualifying symbols.
Labels shall be clearly separated, both horizontally and vertically, from each other and from other symbols or parts ofthe outline with which they are not meant to be associated.Signal-line labels shall also be placed such that they are notlikely to be interpreted as general qualifying symbols.
The preferred location for the general qualifying symbol is in the top of the element to which it applies, centeredhorizontally.An alternative position is centered vertically and horizontally.Application of these positioning rules forthe general qualifying symbols should take into account the positions of embedded elements or labels associated withsignal lines that alter the horizontal area available for placement of the general qualifying symbol.
Labels associated with signal lines shall be centered vertically next to those lines.Horizontally, there shall be a spacebetween the signal-line label and the outline of the symbol or symbols attached to the outline.This horizontal spaceshall be large enough to allow a distinct separation, yet small enough to unambiguously associate the label with thegiven input or output.
See Appendix A for recommended proportions of symbols and IEEE Std 991 for more detailed recommendations onsizes and spacing.
Because of limitations in the publishing systems used, symbols in this document do not always follow the precedingrecommendations.
General additional information may be included in a symbol outline as permitted by an applicable standard forpreparation of diagrams (for example,IEC Publication 111-3 clause 3.4).
For supplementary information relating to the function of a complex logic element, see Section 6.
ln some figures, lowercase letters that are not part of the symbols have been shown outside the outline just to identifythe inputs and outputs as referenced in the description.
Information not standardized in this standard relating to a specific input (output) may be shown in square bracketsinside the outline adjacent to the relevant input(output) and should follow (precede) any qualifying symbols applyingto the input (output), as shown in Symbol 5.13-17.
Other nonstandardized information may also be shown in square brackets inside the symbol outline, for example.Symbols 5.2-3 and 5.4-2.
All outputs of a single, unsubdivided element always have identical internal logic states determined by the function ofthe element except when indicated otherwise by an associated qualifying symbol or label inside the outline.
The subdivision of an element and the qualifying symbols referred to here include those explicitly shown and alsothose only implied according to the simplification rules of 91 pdf download.
