Hitachi Semiconductor America Inc. Hitachi Asia Hong Kong Ltd. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges.

This LED is daatasheet to detect the state of output.

IC Datasheet: 74LS02

TL — Programmable Reference Voltage. Like this we can use each gate of the chip depending on requirement. Where high speed NOR operation is necessary. In that state the current flow through base of dataaheet transistors will be zero.

VCC-Connected to positive voltage to provide power to all four gates.

Copyright ‘ Hitachi, Ltd. Hitachi makes every attempt to ensure that its products are of high quality and reliability. With that the total drop across both transistors will be zero.

Products and product specifications may be subject to change without notice. Even within the guaranteed ranges, 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.

With them the switching delays of gates are minimized. When both buttons are pressed. Even within the guaranteed ranges, consider normally foreseeable.

Now let us consider a adtasheet states: No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without written approval from Hitachi. Confirm that you have received the latest product standards or specifications before final design, purchase or use. Output of the gate is taken out from joint collector of both transistors.

Both transistors will be ON and voltage across both of them will be zero. When you want logic inverter. The four NOR gates in the chip mentioned earlier are connected internally as shown below. 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.

Submitted by admin on 5 April The chip is available in different packages and is chosen depending on requirement. It is really popular and is available everywhere. For realizing the above truth table let us take simplified NOR gate and have it datadheet as shown below. Because of this the chip can be used high speed applications. Dahasheet one of buttons is pressed. This product is not designed to be radiation resistant.

The description for each pin is given below. We can use one or all gates.

The two inputs are driven out from bases of two transistors. The buttons are connected to change the logic of inputs. Hitachi bears no responsibility for failure or damage when used. Confirm that you have.
