In the circuit two transistors are connected to form a NOR gate.

Datasheet «SN54/74LS02»

With that the total drop across both transistors will be zero. TL — Programmable Reference Voltage.

We can use one or all gates. Because of this the chip can be used high speed applications. Submitted by admin on 5 April Where high speed NOR operation is necessary.

Tun-Hwa North Road, Taipei For realizing the above truth table let us take datasehet NOR gate and have it connected as shown below. Output of the gate is taken out from joint collector of both transistors. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges.


Design your application so that the product is used within the ranges guaranteed by Hitachi particularly for maximum rating, operating supply voltage range, heat radiation characteristics, installation conditions and other characteristics.

When one of buttons is pressed. Tokyo 03 Fax: The chip has four NOR gates in it. For further information write to: After verifying the three states, you can tell that we have satisfied the above truth table.

When both buttons are not pressed. Hitachi makes every attempt to datasheeg that its products are of high quality and reliability. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without written approval from Hitachi. Hitachi Semiconductor America Inc. Even within the guaranteed ranges, consider normally foreseeable. It is really popular and is available everywhere. Hitachi bears no responsibility for failure or damage when used.

No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without. Both transistors will be ON and voltage across both of them will be zero. In that state the current flow through base of both transistors will be zero. This LED is connected to detect the state of output. Copyright ‘ Hitachi, Ltd. The description for each pin is given below. The two inputs are driven out from bases of two transistors.

The four NOR gates in the chip mentioned earlier are connected internally as shown below. When you want logic inverter.
