Schematic Symbols
OVERVIEU
This manual and the sixteen TTL Components Schematic Symbol
Diskettes comprise the P-CAD TTL Components Schematic
Symbols Library. The library has been developed at the
request of our users, and we welcome any suggestions
for improvements or additions.
The library diskettes contain the following files for use
with the PC-CAPS schematic capture program:
(
•
Component files
•
Layer structure file, LAYS.SCH
•
Standard-size drawing sheet files, ASIZE.SCH through
ESIZE.SCH
•
7400.FIL and 7400.LIB files
The 7400.FIL file is a sample text file for input into
PREPACK to create the binary file 7400.LIB for packaging
information for PC-PACK. 7400.FIL and 7400.LIB contain
all the components in the TTL Library. Normal usage is
to extract only those components used in a design and put
them in a new .FIL file for input to PREPACK.
Storage of these files in a practical and efficient
directory structure is discussed in the next section of this
manual. The following section, "Creating a Design," tells
you how to use the files with PC-CAPS.
The remainder of the manual is devoted to lists of
components by sequence and function, component pin
sequences, and component plots.
FILE MANAGEMENT
The complete TTL Symbols Library includes more than 4_6 MB
of files. If you are loading the library on the hard disk
of your stand-alone computer, you should omit any of the
technologies that you will not need to conserve disk space.
This is especially important if you are using a 10 MB hard
disk. To make it easy for you to omit the technologies you
do not need, they are supplied on separate floppy disks.
TTL Standard Components
2
If your hard disk space is very limited, you may remove
individual unneeded components from the library. Each
component is contained in a separate DOS file, and
individual components may be erased using the DOS erase
command. Refer to your Disk Operating System (DOS) Manual
or the "DOS Reference" chapter in your PC·CAPS or PC· CARDS
User's Manuals for instructions on listing and erasing
files.
P·CAD recommends a specific directory structure for
efficient system operation. Your library symbols are
normally placed in a specific subdirectory to make it easy
to manage these files. The directory structure is described
in your P·CAD Installation Guide.
CREATING A DESIGN
To use the library in a design, run PC·CAPS. Instructions
are given in the "Using PC· CAPS" chapter of your PC· CAPS
User's Manual. When the menu is displayed, select FILE/LOAD
and load the layer structure. You can load LAYS.SCH or one
of the standard·size drawing sheet files, ASIZE.SCH through
ESIZE.SCH.
Layer Structure
The following layer structure, LAYS.SCH, is a standard P·CAD
layer structure and is recommended when you create library
components.

Dralling Sheets
The standard-size drawing sheet files, ASIZE.SCH through
ESIZE.SCH were created using the LAYS.SCH layer structure.
When loaded, they provide the correct layer structure for
the library plus a standard-size drawing sheet border.

Ca.ponents
When you have loaded your layer structure or drawing sheet
file, you can enter the symbols, wires, text, instances, and
net names. Complete instructions are given in the "Using
PC-CAPS" chapter of your PC-CAPS User's Manual. Each
PC-CAPS component contains the electrical "intelligence"
required to create schematics and extract data.
GENERAL INFORMATION
This library is comprised of symbols from six technoLogies:
1.
2.
3.
4.
5.
6.
Standard
Advanced Low Power Schottky (ALS)
Advanced Schottky (AS)
Fairchild's Advanced Schottky TTL (FAST)
Low Power Schottky (LS)
Schottky (S)
This library was created using the Texas Instruments Inc.
TTL data books, volumes one, two, and three, for most of the
components. The Fairchild Semiconductor FAST data book was
used to create the 74Fnnn components.
Thirty-three OeMorgan Equivalent symbols are included in the
library. These symbols are di fferent i ated by a "0" in thei r
names. For example, 74LS1320.SYM is the OeMorgan Equivalent
of 74LS132.SYM.
The IEEE representations of some devices are contained in
separate files because the IEEE representations could not
fit behind the ANSI representations. The IEEE files are
differentiated by an "E" in their names. For example,
7474E.SYM is the IEEE representation of 7474.SYM.
It was necessary to place the IEEE symbols in separate files
because the amount of text to be drawn inside the symbol
exceeded the standard width of the ANSI symbol. Also for
some symbols the IEEE and the ANSI representations do not
have compatible pin placement. For example, in the case of
flip-flops the ANSI representations show preset and clear at
top and bottom whereas the IEEE representations show them on
the left side of the symbol in the control box.
000-0065-03
Schematic Symbols
Due to system limitations on filename length, the filenames
used for the ALS components are shortened versions of the
component names. For example, 74ALS112A is named
ALS112A.SYM.
NAMING CONVENTIONS
In this library, most of the signal names are drawn exactly
as shown in the data books, but an abbreviated form of the
name may have been entered as the actual signal name. For
example, the signal name READY may visually appear as READY
on the symbol, but its actual entered name may be ROY. The
actual signal names for the symbols are given in the
pinlists in this manual.
Throughout this li,brary the following signal naming
conventions are used.
(a)
(b)
(c)
(d)
(e)

The
CLOCK signal was abbreviated as CPo
/ sign was replaced by a

< sign was replaced by . LT.
COMPONENT LIST BY SEQUENCE
The component filename is the component number plus the
extension .SYM; for example 74LS490.SYM. "Plot Number"
refers to the plots in the last section of this manual.
