Types of Resistor Trimmer Packages


To complement the page covering Potentiometer manufacturers, a link was added to cover Trimmer Packages. So far it just has a few graphics of Trim Pots, through-hole packages. The page is also linked off the Trimmer Definition page. Reference Potentiometer Definition, or here; Potentiometer. Looks like there is a small one for Variable Resistor.

I'll add another page to cover a few surface mount packages soon.

Looks like there's a page for Potentiometer derating, but not one for how to derate a trimmer.

IC Encoders and Converters

Just like the last few page additions, these new links were added to the Functional Schematics page.
The first page covers an Excess-3 Code to Decimal Decoder. I'm a bit unsure what the difference is between an Encoder or Decoder. Couldn't any Encoder be considered a Decoder, depending on if the input or output is being referenced?

Anyway the second addition was for a variation of the same thing; an Excess-3 Gray code to Decimal Decoder.

I also added a link from the 'Ex' Definitions page. I may also add a link to the Definition of Encoders page. Looks like this page is missing a Decoder Definition.

It appears there are now 23 pages in this new section of IC functional diagrams.

Integrated Circuit Functional Diagrams


Added yet more pages today on the topic of functional schematics. These three new pages all cover AND-OR Invert gates. The first is a Dual 2-input AND-OR gate. The next is a Quad 2-Input AND-OR gate. The final is 2-Wide Dual 2-Input AND-OR Invert Expander gate. ~ or something to that effect. Anyway I don't expect any incoming hits, but all the pages are crossed linked. Also they are all linked of the IC Functions page.

I think I also added a page on DIP Switches, or maybe it was last night.

It's not all about three new pages that will see little or no visits, 23 other pages were updated today.

The graphic is a AND-OR Carry Function from a counter.
