<description>&lt;h3&gt;SparkFun Special Function ICs&lt;/h3&gt;
This library contains ICs that do not really fit into the other, more generic categories.  Basically, anything that serves some function but has a bunch of brains or special bias circuitry that prevents it from being used as a general part qualifies for this category.
&lt;p&gt;Contents:
&lt;ul&gt;&lt;li&gt;555 timers&lt;/li&gt;
&lt;li&gt;LED drivers&lt;/li&gt;
&lt;li&gt;H-Bridge drivers&lt;/li&gt;
&lt;li&gt;Motor drivers&lt;/li&gt;
&lt;li&gt;Waveform generators&lt;/li&gt;
&lt;li&gt;Crypto&lt;/li&gt;
&lt;/ul&gt;&lt;/p&gt;&lt;br&gt;
We've spent an enormous amount of time creating and checking these footprints and parts, but it is &lt;b&gt; the end user's responsibility&lt;/b&gt; to ensure correctness and suitablity for a given componet or application.
