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.

Hitachi makes every attempt to ensure that its products are of high quality and reliability. Submitted by admin on 4 April Confirm that you have received the latest product standards or specifications before final design, purchase or use. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly. When you want TTL outputs. Copyright ‘ Hitachi, Ltd.
The gates in this chip provide TTL logic outputs which are a must in some applications. Because base current is zero the transistor will be in OFF state.
No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without written approval from Hitachi. Hex Inverters with Open Collector Outputs. Here are few cases where 74LS04 is used. We have six of these gates in 74LS04 chip.

Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. Tun-Hwa North Road, Taipei Hitachi Semiconductor America Inc. Current through base of transistor will be zero.
Products and product specifications may be subject to change datasgeet notice. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. Output 1Y is connected to LED through a resistor. When button is pressed: 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.

Because base current is present the transistor will turn ON. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. Now let us take a single gate of the six and connect it as shown in circuit diagram. As shown in diagram, we have a transistor forming a NOT gate.
Choose the appropriate package depending on requirement. In the circuit, When button is not pressed: Under OFF sate the total supply voltage appears across the transistor. Confirm that you have. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without.
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 internal connection of gates can be given as below. We can use one or all six of these gates depending on requirement. Hitachi bears no responsibility for failure or damage when used.
The chip has six gates which do NOT operation.
