When you want TTL outputs. No one is permitted to reproduce or duplicate, in any form, the whole or part datawheet this document without written approval from Hitachi. Confirm that you have received the latest product standards or specifications before final design, purchase or use.

For further information write to: Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges.


As shown in diagram, we have a transistor forming a NOT gate. Even within the guaranteed ranges, consider normally foreseeable.

No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without. Input here is 1A which is connected to button. Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor. The chip is basically used where a logic inverter is needed.

Hex Dataaheet with Open Collector Outputs. The series are digital logic integrated circuits.

Tun-Hwa North Road, Taipei Under OFF sate the total supply voltage datqsheet across the transistor. Hitachi makes every attempt to ensure that its products are of high quality and reliability.

Current through base of transistor will be zero. Because base current is present the transistor will turn ON. Copyright ‘ Hitachi, Ltd.

In the circuit, When button is not pressed: If we draw truth table based on above cases, we will datashheet. Tokyo 03 Fax: Now let us take a single gate of the six and connect it as shown in circuit diagram. This product is not designed to be radiation resistant.


Choose the appropriate package depending on requirement.

National Semiconductor

These NOT gates perform Inverting function. The description for each pin is given below.

Hitachi Semiconductor America Inc. The chip has six gates which do NOT operation. The gates in this chip provide TTL logic outputs which are a must in some applications. 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.

The LED is connected to know the output status.
