74LS02 Datasheet

The four NOR gates in the chip mentioned earlier are connected internally as shown below. Now let us consider a few states: We can use one or all gates. Because transistor drop is zero Y1 will be LOW.

Here are a few cases why it is used. Products and product specifications may be subject to change without notice.

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. Hitachi bears no responsibility for failure or damage when used. Tun-Hwa North Road, Taipei In that state the current flow through base of both transistors will be zero.

IC Datasheet: 74LS02

Like this we can use each gate of the chip depending on requirement. Confirm that you have received the latest product standards or specifications before final design, purchase or use. The chip has four NOR gates in it.

The chipis basically used when NOR logic function is required. Hitachi Semiconductor America Inc.

No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without. After verifying the three states, you can tell that we have satisfied the above truth table. Design your application so that the product is used within 74ld02 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. Output of the gate is taken out from joint collector of both transistors.

Because of this the chip can be used high speed applications. This product is not designed to be radiation resistant. Submitted by admin on 5 April With that the total drop across both transistors will be zero. The chip is available in different packages and is chosen depending on requirement. When you want logic inverter.

datasgeet Both transistors will be ON and voltage across both of them will be zero. The buttons are connected to change the logic of inputs.

Hitachi Asia Hong Kong Ltd.

Tokyo 03 Fax: Hitachi makes every attempt to ensure that its products are of high quality and reliability. For realizing the above truth datashfet let us take simplified NOR gate and have it connected as shown below. The two inputs are driven out from bases of two transistors.
