PDF 74LS02 Datasheet ( Hoja de datos )
The chip is available in different packages and is chosen depending on requirement. Even within the guaranteed ranges, consider normally foreseeable. 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.
The buttons are connected to change the logic of inputs. Confirm that you have received the latest product standards or specifications before final design, purchase or use.
The chipis basically used when NOR logic function is required. Tun-Hwa North Road, Taipei Because transistor drop is zero Y1 will be LOW.
For realizing the above truth table let us take simplified NOR gate and have it connected as shown below. Hitachi bears no responsibility for failure or damage when used.
Like this we can use each gate of the chip depending on requirement. Copyright ‘ Hitachi, Ltd. The four NOR gates in the chip mentioned earlier are connected internally as shown below. Here are a few cases why it is used. Even within the guaranteed ranges, consider normally foreseeable failure rates or failure modes in dattasheet devices and employ systemic measures such as fail- safes, so that the equipment incorporating Hitachi product does datashert cause bodily injury, fire or other consequential damage due to operation of the Hitachi product.
Design your application so that the product is used within the ranges guaranteed by Hitachi particularly. The chip has four NOR gates in it. Tokyo 03 Fax: TL — Programmable Reference Voltage. Hitachi makes every attempt to ensure that its products are of high 74ls022 and reliability. It is really popular and is available everywhere. When one of buttons is pressed. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges.
Output of the gate is taken out from joint collector of datasneet transistors.
No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without. Hitachi Semiconductor America Inc. Submitted by admin on 5 April This output is connected to a LED trough a current limiting resistor. These two inputs are connected to buttons.

Products and product specifications may be subject to change without notice. When you want logic inverter. After verifying the three states, you can tell that we have satisfied the above truth table.
When both buttons are not pressed. Where high speed NOR operation is necessary. The two inputs are driven out from bases of two transistors. When both buttons are pressed. This product is not designed to be radiation resistant. Both transistors will be ON and voltage across both of them will be zero. For further information write to: In that state the current flow through base of both transistors will be zero.
With them the switching delays of gates are minimized. Now let us consider a few states: The chip also provides TTL outputs which are a must in some systems. Confirm that you have. With that the total drop across both transistors will be zero.
No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without written approval from Hitachi. We can use one or all gates.
74LS02 NOR Gate IC Pinout, Features, Equivalents, Circuit & Datasheet
This LED is connected to detect the state of output. Hitachi Asia Hong Kong Ltd.
Because of this the chip can be used high speed applications. VCC-Connected to positive voltage to provide power to all four gates. The description for each pin is given below. In the circuit two transistors are connected to form a NOR gate.
