DIGITAL CHIPS!

Digital Electronics devices are usually in a chip format.

The chip is identified with a part number or a model number.

A standard series starts with numbers 74, 4, or 14:

                       7404 is an inverter

            7408 is an AND

                              7432 is an OR

                              4011B is a NAND

     Basic logic chips often come in 14-pin packages.

     Package sizes and styles vary.

     Pin 1 is indicated with a dot or half-circle

   Numbers are read counter-clockwise from pin 1

     Chips require a voltage to function

     Vcc is equal to 5 volts and is typically pin 14

     Ground is typically pin 7

The voltage and ground pins must be connected for the device to function.
