Something else about IC's and their representation in schematics...
Very often, you will find the pins arranged in a "flow" manner, with all of the various "input" pins drawn on the left side of the device, all of the "output" pins drawn on the right side of the device, with supply voltage at the top, and with ground at the bottom.
To see what I mean, take a look at the schematic symbol for the LMD18201 below. This is typical of the device symbols supplied with many software packages -- this one happens to be from ExpressSchematic.
