IC 7408



IC 7408 is a logic gate IC. It consists of four two-input AND Gates. The AND gate performs logical AND operation. Logic gates come in the form of ICs. All four AND gates are independent. Each gate has three pins two inputs and one output. IC 74HC08, and IC DM7408 are AND gate ICs.

Pin diagram of IC 7408:



The IC 7408 has a total of fourteen pins including ground and Vcc. The simple pin diagram is shown below.

Operating Condition of IC DM7408 :


  • The power supply should be given to the IC from 4.5V DC to 5.25V DC
  • The IC can identify a signal as a high-level signal if the voltage of the signal is above 2V
  • The IC can identify a signal as a low-level signal if the voltage of the signal is below 0.8V
  • The IC should be operated below the 70-degree centigrade

Characteristics:


  • The IC DM7408 can deliver a 21 mA current when the output signal is high at maximum Vcc Voltage.
  • The IC can deliver 33 mA current when the output signal is low at maximum Vcc voltage.
  • When the Vcc is maximum and the input signal is 5.5V then the IC draws 1 mA current.
  • When the Vcc is maximum and the input signal is 2.7V then the IC draws 20 to 40 micro-ampere currents.
  • When the Vcc is maximum and the input signal is 0.4V  then the IC draws -1.6 mA current.
