PDF 74LS04 Datasheet ( Hoja de datos )

When button is pressed: The series are digital logic integrated circuits. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without. The gates in this chip provide TTL logic outputs which are a must in some applications. Hitachi bears no responsibility for failure or damage when used. Confirm that dagasheet have.

Under OFF sate the total supply voltage appears across the transistor.

Design your application so that the product datashdet 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 4 April Output 1Y is connected to LED through a resistor. Hex Inverters with Open Collector Outputs.


74LS04 Datasheet

The internal connection of gates can be given as below. When you want TTL outputs. Here are few cases where 74LS04 is used. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. Choose the appropriate package depending on requirement.

Calaméo – Datasheet – 74LS04

The description for each pin is given below. Confirm that you have received the latest product standards or specifications before final design, purchase or use.

Now let us take a single gate of the six and connect it as shown in circuit diagram. Input here is 1A which is connected to button. For further information write to: If we draw truth table based on above cases, we will have.

We can use one or all six of these gates depending on requirement. This datasheet has been downloaded from: 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. Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor.

Current through base of transistor will be zero. Even within the guaranteed ranges, consider normally foreseeable. The LED is connected to know the output dattasheet. Copyright ‘ Hitachi, Ltd.


Devices also available in Tape and Reel. Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. Because base current is 74ls40 the transistor will be in OFF state. Not more than one output should be shorted at a time.

The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. Life support devices or systems are devices or systems which, a are intended for surgical implant into the body, or b support or sustain life, and c whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury to the user.

Hitachi Semiconductor America Inc. Inverter Gates in this chip provide output which is negated logic input. The chip has six gates which do NOT operation. Hitachi makes every attempt to ensure that its products are of high quality and reliability.
