PDF 74LS02 Datasheet ( Hoja de datos )

Tun-Hwa North Road, Taipei Hitachi bears no responsibility for failure or damage when 74ls2. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. 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. Now let us consider a few states: Both transistors will be ON and voltage across both of them will be zero. Because of this the chip can be used high speed applications.

It is really popular and is available everywhere. Tokyo 03 Fax: 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. Where high speed NOR operation is necessary. The buttons are connected to change the logic of inputs.

Hitachi Semiconductor America Inc. In the circuit two transistors are connected to form a NOR gate. Because transistor drop is zero Y1 will be LOW. The two inputs are driven out from bases of two transistors.

After verifying the three states, you can tell that we have satisfied the above truth table. In that state the current flow through base of both transistors will be zero. When both buttons are pressed.

Hitachi Asia Hong Kong Ltd. For further information write to: When you want logic inverter. Hitachi makes every attempt to ensure that its products are of high quality and reliability.

The chip has four NOR gates in it.

Even within the guaranteed ranges, consider normally foreseeable. These two inputs are connected to buttons. Copyright ‘ Hitachi, Ltd.

Products and product specifications may be subject to change without notice. Output of the gate is taken out from joint collector of both transistors. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly.

The chipis basically used when NOR logic function is required.
