74LS02 Datasheet

In the circuit two transistors are connected to form a NOR gate. When you want logic inverter.

Tun-Hwa North Road, Taipei This output is connected to a LED trough a current limiting resistor. With them the dataeheet delays of gates are minimized.

Hitachi bears no responsibility for failure or damage when used. The description for each pin is given below. These two inputs are connected to buttons. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly.

This LED is connected to detect the state of output. In that state the current flow through base of both transistors will be zero. Hitachi Semiconductor America Inc.

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 dwtasheet other consequential damage due to operation of the Hitachi product. Products and product specifications may be subject to change without notice. Confirm that you have received the latest product standards or specifications before final design, purchase or use.

Because transistor drop is zero Y1 will be LOW. Now let us consider a few states: The two inputs are driven out from bases of two transistors.

Hitachi Asia Hong Kong Ltd. TL — Programmable Reference Voltage. Tokyo 03 Fax: Hitachi makes every attempt to ensure that its products are of high quality and reliability. This product is not designed to be radiation resistant. The chip is available in different packages and is chosen depending on requirement. Here are a few cases why it is used. The chipis basically used when NOR logic function is required.

With that the total drop across both transistors will be zero.

Confirm that you have. It is really popular and is available everywhere. Output of the gate is taken out from joint collector of both transistors. Submitted by admin on 5 April After verifying the three states, you can tell that we have satisfied the above truth table.

When both buttons are not pressed. The buttons are connected to change the logic of inputs. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges.

74LS02 NOR Gate IC Pinout, Features, Equivalents, Circuit & Datasheet

daatsheet Copyright ‘ Hitachi, Ltd. When both buttons are pressed. Both transistors will be ON and voltage across both of them will be zero. 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.
