This output is connected to a LED trough a current limiting resistor. Even within the guaranteed ranges, consider normally foreseeable. Products and product specifications may be subject to change without notice. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without.
Now let us consider a few states: Hitachi Semiconductor America Inc. It is really popular and is available everywhere.
Tun-Hwa North Road, Taipei The description for each pin is given below. This product is not designed to be radiation resistant. Because of this the chip can be used high speed applications. Because transistor drop is zero Y1 will be LOW. The four NOR gates in the chip mentioned earlier are connected internally as shown below.
74LS02 Hoja de datos ( Datasheet PDF ) – Quadruple 2-input Positive NOR Gates
Hitachi bears no responsibility for failure 74la02 damage when used beyond the guaranteed ranges. In the circuit two transistors are connected to form a NOR gate. For further information write to: Where high speed NOR operation is necessary.
Hitachi makes every attempt to ensure that its products are of high quality and reliability. The buttons are connected to change the logic of inputs.
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. Confirm that you have. No one is permitted to reproduce or duplicate, in any form, the whole or part of this datxsheet without written approval from Hitachi.

The two inputs are driven out from bases of datasgeet transistors. Hitachi bears no responsibility for failure or damage when used. Copyright ‘ Hitachi, Ltd. Like this we can use each gate of the chip depending on requirement. Both transistors will be ON and voltage across both of them will be zero.
When one of buttons is pressed. When both buttons are pressed. TL — Programmable Reference Voltage. This LED is connected to detect the state of output. The chipis basically used when NOR logic function is required. Hitachi Asia Hong Kong Ltd.

fatasheet The chip has four NOR gates in it. Here are a few cases why it is used. For realizing the above truth table let us take simplified NOR gate and have it connected as shown below.
The chip also provides TTL outputs which are a must in some systems. In that state the current flow through base of both transistors will be zero.
Confirm that you have received the latest product standards or specifications before final design, purchase or use. Output of the gate is taken out from joint collector of both transistors.
When both buttons are not pressed. The chip is available in different packages and is chosen depending on requirement. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly.
