Note The ”Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaran- teed The device should not be operated at. µA. VCC = MAX, VIN = V. IIH. Input HIGH Current. mA. VCC = MAX, VIN = V. IIL. Input LOW Current. – mA. VCC = MAX, VIN = V. IOS. 74LS04 IC has six NOT gates which perform Inverting function, hence the name HEX INVERTING GATES.

The description for each pin is given below. Choose the appropriate package depending on requirement. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without written approval from Hitachi.

Datasheet – 74LS04

If we draw truth table based dstasheet above cases, we will have. Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor. Tun-Hwa North Road, Taipei We can use one or all six of these gates depending on requirement. The series are digital logic integrated circuits.

Current through base of transistor will be zero. Hitachi Asia Hong Kong Ltd.

This product is not designed to be radiation resistant. Recommended Operating Conditions Electrical Characteristics over recommended operating free air temperature range unless otherwise noted Note 2: Submitted by admin on 4 April Because base current is datawheet the transistor will turn ON.

Confirm that you have. Input here is 1A which is connected to button. Inverter Gates in this chip provide output which is negated logic input. 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.

The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.

Calaméo – Datasheet – 74LS04

These NOT gates perform Inverting function. Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero.

Datasehet ‘ Hitachi, Ltd. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without. A critical component in any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.

Even within the guaranteed ranges, consider normally foreseeable. Now let us take a single gate of the six and connect it as shown in circuit diagram. Not more than one output should be shorted at a time. Confirm that you have received the latest dxtasheet standards or specifications before final design, purchase or dataheet.

For further information write to: Here are few cases where 74LS04 is used. TL — Programmable Reference Voltage. Under OFF sate the total supply voltage appears across the transistor.

Tokyo 03 Fax: The device should not be operated at these limits. The LED is connected to know the output status. Output 1Y is connected to LED through a resistor.

Hitachi bears no responsibility for failure or damage when used. 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 74os04 Hitachi product does not cause bodily injury, fire or other consequential damage due to operation of the Hitachi product.

Products and product specifications may be subject to change without notice. Devices also available in Tape and Reel. The internal connection of gates can be given datasneet below. 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.

The chip is basically used where a logic inverter is needed. Hex Inverters with Open Collector Outputs.

74LS04 Datasheet, PDF – Alldatasheet

Because base current is zero the transistor will be in OFF state. In the circuit, When button is not pressed: This datasheet has been downloaded from: Hitachi makes every attempt to ensure that its products are of high quality and reliability.

The datasjeet in this chip provide TTL logic outputs which are a must in some applications. Hitachi Semiconductor America Inc. When you want TTL outputs.

Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. Voltage appears at base of transistor datassheet current flows through it. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges.

When button is pressed: We have six of these gates in 74LS04 chip.
