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.

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 chip has six gates which do NOT operation. 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.

We can use one or all six of these gates depending on requirement. Hitachi Semiconductor America Inc. Current through base of transistor will be zero.

The LED is connected to know the output status.

Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. We have six of these gates in 74LS04 chip.

TL — Programmable Reference Voltage. The gates in this chip provide TTL logic outputs which are a must in some applications. Tokyo 03 Fax: Hitachi bears no responsibility for failure or damage when used. Voltage appears at base of transistor and current flows through it. Submitted by admin on 4 April Hitachi Asia Hong Kong Ltd.

Choose the appropriate package depending on requirement. The internal connection of gates can be given as below. The description for each pin is given below. The chip is basically used where a logic inverter is needed.

These NOT gates perform Inverting function. Now 74ps04 us take a single gate of the six and connect it as shown in circuit diagram. Hitachi makes every attempt to ensure that its products are of high quality and reliability.

74LS04 Datasheet

Under such case the output 1Y here will dataheet HIGH, since output is nothing but voltage across transistor. Output 1Y is connected to LED through a resistor. Confirm that you have. Here are few cases where 74LS04 is used. In the circuit, When button is not pressed: Products and product specifications may be subject to change without notice.

Under OFF sate the total supply voltage appears across the transistor. If we draw truth table based on above cases, we will have. Hex Inverters with Open Collector Outputs.

This product is not designed to be radiation resistant. Under such case the output 1Y here will also be LOW, since output is nothing datazheet voltage across transistor.

Design your application so that the product is used within the ranges guaranteed by Hitachi particularly. Confirm that you have received the latest product standards or specifications before final design, purchase or use.

National Semiconductor

Because base current is zero the transistor will be in OFF state. As shown in diagram, we have a transistor forming a NOT gate. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without written approval from Hitachi.

For further information write to: The series are digital logic integrated circuits. Because datadheet current is present the transistor will turn ON. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without. Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. When button is pressed: Copyright ‘ Hitachi, Ltd.

Inverter Gates in this chip provide output which is negated logic input. When you want TTL outputs. Even within the guaranteed ranges, consider normally foreseeable. Tun-Hwa North Road, Taipei 74lw04 Input here is 1A which is connected to button.
