Design your application so that the product is used within the ranges guaranteed by Hitachi particularly. The chip is available in different packages and is chosen depending on requirement. When you want logic inverter. The chip has four NOR gates in it.

These two inputs are connected to buttons. Now let us consider a few states: This LED is connected to detect the state of output.

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. 74ls2 and dayasheet 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.

This output is connected to a LED trough a current limiting resistor. When one of buttons is pressed.

With that the total drop across both transistors will be zero. It is really popular and is available everywhere.

Copyright ‘ Hitachi, Ltd. VCC-Connected to positive voltage to provide ddatasheet to all four gates. With them the switching delays of gates are minimized. The description for each pin is given below.

Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. When both buttons are pressed.

Even within the guaranteed ranges, consider normally foreseeable. Hitachi Asia Hong Kong Ltd. For further information write to: Hitachi makes every attempt to ensure that its products are of high quality and reliability. When both buttons are not pressed.

Even within the guaranteed fatasheet, consider normally foreseeable failure rates or failure modes in semiconductor devices and employ systemic measures such as fail- safes, so that the equipment incorporating Hitachi product does not cause bodily injury, fire or other consequential damage due to operation of the Hitachi product. Tun-Hwa North Road, Taipei Both transistors will be ON and voltage across both of them will be zero.

This product is not designed to be radiation resistant. In that state the current flow through base of both transistors will be zero. The two inputs are driven out from bases of two transistors. The chip also provides TTL outputs which are a must in some systems.

Submitted by admin on 5 April Because transistor drop is zero Y1 will be LOW. Here are a few cases why it is used. TL — Programmable Datsheet Voltage.

74LS02 Hoja de datos ( Datasheet PDF ) – Quadruple 2-input Positive NOR Gates

Because of this the chip can be used high speed applications. After verifying the three states, you can tell that we have satisfied the above truth table. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without written approval from Hitachi.

Output of the gate is taken out from joint collector of both transistors. We 74l0s2 use one or all gates. Like this we can use each gate of the chip depending on requirement.

The four NOR gates in the chip mentioned earlier are connected internally as shown below. Hitachi bears no responsibility for failure or damage when used. Where high speed NOR operation is necessary. In the circuit two transistors are connected to form a NOR gate. The buttons are connected to change the logic of inputs. The chipis basically used when NOR logic function is required. Hitachi Semiconductor America Inc.

Tokyo 03 Fax: Confirm that you have. Confirm that you have received the latest product standards or specifications before final design, purchase or use.

Datsheet realizing the above truth table let us take simplified NOR dwtasheet and xatasheet it connected as shown below.
