7404 NOT بوابة 5V 24mA IC DIP-14

7404 ليس بوابة ZKEEP0Z ZKEEP1Z IC DIP-14

The 7404 is a high-speed TTL (Transistor-Transistor Logic) integrated circuit featuring six independent inverters (NOT gates) in a 14-pin Dual In-Line Package (DIP-14). Each gate performs logical inversion: when the input is HIGH, the output is LOW, and vice versa. This IC is widely used in digital electronics for signal inversion, logic-level shifting, and oscillator circuits.

سمات:

شرح الدائرة :

When switch is off, input pin of NOT gate will get connected to ground through the pull down resistor. Gate will consider it as logical LOW, So output will be HIGH and LED will turn ON. If the input pin is left unconnected ( not connected to pull down resistor and switch ), IC will assume itself that, voltage at the gate input is logical HIGH. So, turning off the switch without connecting pull down resistor will not give logical LOW at the input. That is, switch will have no effect in changing the voltage level at the gate input if pull down resistor is not connected. Similarly, when the switch turns on, voltage across the input pin will be ZKEEP0Z. Gate will consider it as logical HIGH. so the output will be logical LOW. This will turn off the LED. A current limiting resistor is provided in series with LED to protect LED from overcurrent. Truth table of this circuit is given below.
