Operating Condition of IC 7400:


1.      The IC 7400 can operate from 4.5V Dc to 5.25V DC voltage. So power supply to the IC should be given in that range.
2.      It can identify a signal as a high signal if the signal has the voltage above 2V.
3.      It can identify a signal as a low signal if the signal has the voltage below 0.8V
4.      The Ic 7400 can withstand up to 70-degree centigrade temperature so the operating temperature should be below that temperature.




Electrical Characteristics:


1.      The high-level input current is 20 micro-ampere at maximum Vcc and input voltage 2.7V
2.      The low-level input current is -0.36 mA at maximum Vcc and input voltage 0.4V
3.      Supply current with output HIGH is 1.6 mA at Maximum Vcc
4.      Supply current with output LOW is 4.4 mA at Maximum Vcc
5.      The short circuit output current is -20 to -100 mA at maximum Vcc
