Because of this the chip can be used high speed applications. These two inputs are connected to buttons. The four NOR gates in the chip mentioned earlier are connected internally as shown below. This LED is connected to detect the state of output.
After verifying the three states, you can tell that we have satisfied the above truth table. In the circuit two transistors are connected to form a NOR gate. Even within the guaranteed ranges, consider normally foreseeable.
When both buttons are pressed.
The chipis basically used when NOR logic function is required. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without. The buttons are connected to change datasheet logic of inputs.
74LS02 NOR Gate IC Pinout, Features, Equivalents, Circuit & Datasheet
The chip has four NOR gates in it. Confirm that you have received the latest product standards or specifications before final design, purchase or use. Submitted by admin on 5 April This output is connected to a LED trough a current limiting resistor.
Design your application so that the product is used within dwtasheet ranges guaranteed by Hitachi particularly. This product is not datashdet to be radiation resistant. VCC-Connected to positive voltage to provide power to all four gates. TL — Programmable Reference Voltage. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. Hitachi bears no responsibility for failure or damage when used. The description for each pin is given below.
It is really popular and is available everywhere.

With that the total drop across both transistors will dxtasheet zero. When you want logic inverter. In that state the current flow through base of both transistors will be zero. For realizing the above truth table let us take simplified Datasneet gate and have it connected as shown below. The two inputs are driven out from bases of two transistors.

The chip is available in different packages and is chosen depending on requirement. Tun-Hwa North Road, Taipei With them the switching delays of gates are minimized.
Both transistors will be ON and voltage across both of them will be zero. Like this we can use each gate of the chip depending on requirement. When both buttons are not pressed. Tokyo 03 Fax: Here are a few cases why it is used.
