What is the Use of 7408 IC?
a 7408 ic chip is a quadruple, 2 input AND Gate chip. These
chips have 14 pins. Pin 7 is gnd and pin 14 is vcc. In principle,
an AND Gate is just that. A gate that is Active high. To get an
active high output, you must have both inputs active high. 5 volts
on each input will give you a 5 volt output. These IC chip use TTL
(transistor-transistor logic). They are obsolete and are no longer
used in todays electrical circuits. Most electronic systems use a
large CPLD, Complex Programmable Logic Device, that can be used to
implement digital logic designs that contain 20,000 or fewer gates.
Texas Instruments poineered the TTL 7408 IC chip. CPLD boards are
commonly made by a company named Altera
