Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor.

Hitachi Semiconductor America Inc. Choose the appropriate package depending on requirement.

Inverter Gates in this chip provide output which is negated logic input.

Current through base of transistor will be zero. If we draw truth table based on above cases, we will have. Tokyo 03 Fax: 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.

Now let us take a single gate of the six and connect it as shown in circuit diagram. Because base current is zero the transistor will be in OFF state. Hitachi makes every attempt to ensure that its products are of high quality and reliability.

When you want TTL outputs. No one is permitted to reproduce or duplicate, in any form, datashheet whole or part of this document without. In the circuit, When button is not pressed: Hitachi Asia Hong Kong Ltd. Hitachi bears no responsibility for failure or damage when used. Output 1Y is connected to LED through a resistor.

Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. 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.

Even within the guaranteed ranges, consider normally foreseeable.

Voltage appears at base of transistor and current flows through it. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly.

Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor. Confirm that you have received the latest product standards or specifications before final design, purchase or use. Confirm that you have.

National Semiconductor – datasheet pdf

Input here is 1A which is connected to button. These NOT gates perform Inverting function. As datasyeet in diagram, we have a transistor forming a NOT gate. We have six of these gates in 74LS04 chip.
