74LS02 Datasheet

Design your application so that the product is used datasheett the ranges guaranteed by Hitachi particularly. Tokyo 03 Fax: With them the switching delays of gates are minimized.

Now let us consider a few states: For realizing the above truth table let us take simplified NOR gate and have it connected as shown below. The four NOR gates in the chip mentioned earlier are connected internally as shown below.

Like this we can use each gate of the chip depending on requirement. VCC-Connected 74ls0 positive voltage to provide power to all four gates.

The chip is available in different packages and is chosen depending on requirement. Both transistors will be ON and voltage across both of them will be zero. No one is permitted to reproduce or duplicate, datashewt any form, the whole or part of this document without.

Hitachi bears no responsibility for failure or damage when used.

TL — Programmable Reference Voltage. In that state the current flow datashdet base of both transistors will be zero. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. The chipis basically used when NOR logic function is required.

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.

The buttons are connected to change the logic of inputs.

Dataseet Semiconductor America Inc. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without written approval from Hitachi.

With that the total drop across both transistors will be zero. When both buttons are pressed. The chip also provides TTL outputs which are a must in some systems. Output of the gate is taken out from joint collector of both transistors. Design your application so that the product is dwtasheet within the ranges guaranteed by Hitachi particularly for maximum rating, operating supply voltage range, heat radiation characteristics, installation conditions and other characteristics.

Submitted by admin on 5 April Products and product specifications may be subject to change without notice. We can use one datashwet all gates.

This LED is connected to detect the state of output. Confirm that you have received the latest product standards or specifications before final design, purchase or use. The dafasheet for each pin is given below. Because transistor drop is zero Y1 will be LOW.

Hitachi makes every attempt to ensure that its products are of high quality and reliability. When both buttons are not pressed.
