Therrysa 5. Da-young 5. Name the file what ever you want then type. The default options are fine. Once this is done check the PDF file to be sure everything looks right and print the file. I always go back into gimp at this point and change from the layers dock on the right to the undo history tab.

I then reset the history to the marker just before I created the 8. This is by-far the fastest way to reduce the size of the canvas and entire file to keep it manageable despite having so many layers, and complexity. Start off with the datasheet pin-out in view.

Duplicate one of the blank templates with the correct pin count. Templates are in a folder at the bottom of the Files folder. Copy the layer and take it to the top. Next you will find a folder called FAB that has line guides I use to make labels. It's set up to establish the location of each line of text, and the center line of every pin. The best way to see how I use this guide layer is to look at one of the more simple completed labels from the Series.

The top and bottom of the FAB guide has a couple of colored semi opaque lines that delineate where the Pin number text belongs. This text is size 65 Ubuntu-Bold with the letter spacing set to -2 on all newer style labels. Next, there are two thick green bars on the FAB guide. These are for the Inverted bars that go above Pin descriptions.

The bar height is the minimum thickness for the bars to show up on my printers. I make a box the width of the pin name and use the green bar to locate it vertically, then fill the box with the paint tool. I always try to make the bars 2 pixels taller than the green guide. Next, in the middle of the green bar there is a darker green line. This is the top guide for the height of pin text. There is another line guide below. This is setup for two text sizes.

With the Ubuntu-Bold font selected, I use a size 60 font for most 2 character pin names. If you look at the FAB guide layer, I have a copy of the entire alphabet and numerals with funny coloring. This is split to show which numbers and letters extend onto the text guide lines.

The letters with green or red overlap the line on one side or the other. This just keeps everything centered straight and uniform for each label. I mentioned this text guide is for two sizes of text.

The second size is 52 instead of I only use the lower guide line for this size text. Size 52 will place the text just below the inverted bar guide. This is also my standard text size for anything longer than 2 characters. I try to limit pin text to these two sizes but occasionally I use a size 48 for something really wide. Size 45 is the smallest that I can print and read most of the time. I have made a few labels that even have size 35 text, but it is challenging to get this to print legibly.

The center of the FAB guide label area has a few yellow lines. These are my guidelines for centering the part number and title. I use Ubuntu-Bold-Italic for all of this text. I try to always print this text in size although it is tough to fit sometimes. I set the character width spacing to the smallest I can manage without letting the letters touch each other.

There are also several templates saved in the FAB guide layer. This is where I make and save a copy of gates, truth tables or anything else I've tried and might want to reuse later. I also have a bunch of custom fonts made with the letter Q and the sizes of text I use marked below them. This is specifically because the upper case Ubuntu font's "Q" is the only letter that extends below the bottom boundary of the rest of the letters in the font.

This creates lots of interference issues. Of the dozens of fonts I tried none of them print as well as Ubuntu in the required size range. Most fonts that have a more compact capital Q print like a zero or O at the sizes required. I just use the regular Ubuntu-Bold Q font when I'm making the text for a label.

Once I have everything setup where I want it, I go back and align the copied custom Q's over the typed Q. The circumference of the custom Q is identical to the same size Ubuntu font. The exaggerated cross of the custom Q and the gap makes it quite definitive even at the smallest sizes. It also has a much more manageable lower extension for fitting more text in tight spaces. Where do I get my pin descriptions? They are usually based on a combination of Texas Instruments, Motorola, and Fairchild datasheets.

I often use the old databooks directly. If you are not aware, Archive. I don't commit to following any specific datasheet pin nomenclature though. If the nomenclature requires me to look at a datasheet description to figure out it's basic meaning or function I won't use it assuming I can think of something more obvious and intuitive. I think "G" was intended to mean "gate" for the enable function.

I don't like it. I'm moving towards even more detailed ways of labeling special function pins by replacing the pin number with 2 lines of text. I generally try to avoid using O. I will use Y for gate outputs, and use Q like a crossed O or O-proper for an output. I just don't want to wonder if I'm looking at a zero or O.

In most instances where there are 8 pins, I label them like the buses they are most likely to be used with. Also of note, there are several labels with various alternate versions. I usually made one, didn't like it, or wanted to see if I could fit more functionality. I just kept the old version too. It might be useful to someone with a lower resolution printer.

There are several labels with a NAR ending. These are narrow versions. It means the inventory I have has the narrow half pin end with the shortened body without much overhang beyond the last pins. My regular labels hang over the ends of these chips by around 1mm on both sides.

They are still functional, but it just bugs me so I started making a narrow version that fits tighter. As of January 28th , I have started making a 3rd type of label. These use a new template set named hybrid. This template is setup between the standard original and Narrow size templates. Specifically, with the resolution setup in GIMP pixels is 0. The Standard template extends past the corner pins by 55 pixels from the corner pins' center line to the center of the template outline.

This means the hybrid may still extend slightly over the edge of some narrow chips, but is a way for me to make some of these things faster. It is easiest to make labels in the standard size where less specific adjustments are needed to fit text. Narrow usually requires far more manipulation.

Hybrid is just a happy medium. Lastly, It should go without saying If you find an error before I do, feel free to let me know.
