Here you'll find data sheets and information on the integrated circuits we're using in class.

The most important part of a data sheet is the pinout diagram (typically first in the data sheet), showing which pins are connected to what. The pins used to power the chip are often labeled Vcc and Gnd. Vcc is another term for the positive side of power. This is the power from the red line (+5 volts) on the breadboards. (It stands for Voltage Collector Collector, a reference to the transistor-based implementation.) Gnd is ground, in other words the negative side of power. This is the blue line on the breadboards.

For example, on the 7404 data sheet you'll see that pin 7 is labeled Gnd and should be connected to the blue side and pin 14 is Vcc and goes to red. This corner-oriented power configuration is nearly universal for all the 74xx integrated circuits.

Pay special attention to the notch in the end of the integrated circuit package. This indicates where pin 1 is. (Sometimes instead of a notch it's a round depression.) Integrated circuits tend to get hot and smelly when they're wired wrong (and they don't do what they're supposed to).

• 74xx TOC - 74xx series table of contents.
• 7400 - Four NAND gates (commonly called a Quad 2-input NAND).
• 7404 - Six NOT gates (commonly called a Hex Inverter, but not because it undoes spells).
• 7408 - Four AND gates (Quad 2-input AND).
• 7432 - Four OR gates (Quad 2-input OR).
• 7486 - Four XOR gates (Quad 2-input XOR).
• 74193 - 4-bit binary up/down counter.
• 74283 - 4-bit binary adder.
• 74374 - One whole byte (Octal flip-flop).
• 2016 - 2Kx8 static RAM (chip says "4016" but it's the same thing).
• 555 - 555 timer.
• 555 Notes - 555 timer class notes

Joe's big list of integrated circuit datasheets can be found here. I'll attach the ones that are relevant to class as they're introduced.
