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.

We have six of these gates in 74LS04 chip. Tokyo 03 Fax: This product is not designed to be radiation resistant. Here are few cases where 74LS04 is used. Inverter Gates in this chip provide output which is negated logic input.
Tun-Hwa North Road, Taipei When button is pressed: Current through base of transistor will be zero. Products and product specifications may be subject to change without notice. As shown in diagram, we have a transistor forming a NOT gate. 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.
When you want TTL outputs. Under such case the output dtaasheet here will also be LOW, since output is nothing but voltage across transistor. Output 1Y is connected to LED through a resistor. If we draw truth table based on above cases, we will have.
For further information write to: Because base current is zero the transistor will be in OFF state. Input here is 1A which is connected to button.
Hitachi Semiconductor America Inc. Confirm that you have. Under OFF sate the total supply voltage appears across the transistor. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. Choose the appropriate package depending on requirement. No one is permitted to reproduce or duplicate, in datxsheet form, the whole or part of this document without.
74LS04 NOT Gate IC | IC Datasheet
Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. 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 datasheey does not cause bodily injury, fire or other consequential damage due to operation of the Hitachi product.
Hitachi Asia Hong Kong Ltd. The LED is connected to know the output status.
Hitachi bears no responsibility for failure or damage when used. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without datzsheet approval from Hitachi.
Submitted by admin on 4 April The chip is basically used where a logic inverter is needed. Voltage appears at base of transistor and current flows through datssheet. Hex Inverters with Open Collector Outputs. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor.
We can use one or all six of these gates depending on requirement. Because base current is present the transistor will turn ON.

Hitachi makes every attempt to ensure that its products are of high quality and reliability. Confirm that you have received the latest product standards or specifications before final design, purchase or use. TL — Programmable Dafasheet Voltage.
The internal connection of gates can be given as below. Copyright ‘ Hitachi, Ltd. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly.
Even within the guaranteed ranges, consider normally foreseeable.
The series are digital logic integrated circuits.
