These NOT gates perform Inverting function. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. Now let us take a single gate of the six and connect it as shown in circuit diagram. Hitachi bears no responsibility for failure or damage when used. Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor.
Choose the appropriate package depending on requirement. We can use one or all six of these gates depending on requirement.
Hitachi makes every attempt to ensure that its products are of high quality and reliability. Confirm that you have. Under OFF sate the total supply voltage appears across the transistor. When button is pressed: Because base current is zero the transistor will be in OFF state. The series are digital logic integrated circuits.
Hitachi Asia Hong Kong Ltd. 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 chip is basically used where a logic inverter is needed. Products and product specifications may be subject to change without notice. Inverter Gates in this chip provide output which is negated logic input.
The description for each pin is given 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. This product is not designed to be radiation resistant.
Hitachi Semiconductor America Inc. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly.

Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. Input here is 1A which is connected to button. The gates in this chip provide TTL logic outputs which are a must in some applications. Even within the guaranteed ranges, consider normally foreseeable.
Because base current is present the transistor will turn ON.
As shown in diagram, we have a transistor forming a NOT gate. If we draw truth table based on above cases, we will have.
