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.

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

As shown in diagram, we have a transistor forming a NOT gate. For further information write to: Datasheft makes every attempt to ensure that its products are of high quality and reliability. These NOT gates perform Inverting function.

Here are few cases where 74LS04 is used. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. The description for datqsheet pin is given below. Hitachi Semiconductor America Inc. The internal connection of gates can be given as below. Under OFF sate the total supply voltage appears across the transistor.

Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. In the circuit, When button is not pressed: Products and product specifications may be subject to change without notice.

Hex Inverters with Open Collector Outputs. This product is not designed to be radiation resistant. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. Hitachi bears no responsibility for failure or damage when used. Choose the appropriate package depending on requirement. The LED is connected to know the datsaheet status.

Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor. Hitachi Datashedt Hong Kong Ltd.

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.

Design your application so that the datasgeet is used within the ranges guaranteed by Hitachi particularly. 744ls04 let us take a single gate of the six and connect it as shown in circuit diagram.

Confirm that you have received the latest product standards or specifications before final design, purchase or use. Tokyo 03 Fax: The gates in this chip provide TTL logic outputs which are a must in some applications. The series are digital logic integrated circuits.

We can use one or all six of these gates depending on requirement. Because base current is present the transistor will turn ON. The chip has six gates which do NOT operation. If we draw truth table based on above cases, we will have. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without written datasheeh from Hitachi. Input here is 1A which is connected to button.

When you want TTL outputs.

Tun-Hwa North Road, Taipei When button is pressed: Voltage appears at base of transistor and current flows through it. We have six of these gates in 74LS04 chip. 74l0s4 within the guaranteed ranges, consider normally foreseeable failure rates or failure modes in semiconductor devices and employ systemic measures such as datasheet 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.

Output 1Y is connected to LED through a resistor. TL — Programmable Reference Voltage. The chip is basically used where a logic inverter is needed. Even within the guaranteed ranges, consider normally foreseeable. Current through base of transistor will be zero.
