Confirm that you have received the latest product standards or specifications before final design, purchase or use. Hitachi bears no responsibility for failure or damage when used. Choose the appropriate package depending on requirement. When you want TTL outputs. The gates in this chip provide TTL logic outputs which are a must in some applications.

If we draw truth table based on above cases, we will have. No one 74le04 permitted to reproduce or duplicate, in any form, the whole or part of this document without.

Submitted by admin on 4 April Current through base of transistor will be zero. When button is pressed: Copyright ‘ Hitachi, Ltd. Output 1Y is connected to LED through a resistor. Under OFF sate the total supply voltage appears across the transistor.

These NOT gates perform Inverting function. Input here is 1A which is connected to button. We can use one or all six of these gates depending on requirement. Hitachi makes every attempt to ensure that its products are of high quality and reliability.

National Semiconductor

Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor.

Voltage appears at base of transistor and current flows datashedt it. Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero.

Hitachi Asia Hong Kong Ltd. Tokyo 03 Fax: Because base current is present the transistor will turn ON.

Now let us datadheet a single gate of the six and connect it as shown in circuit diagram. The chip is basically used where a logic inverter is needed. Even within the guaranteed ranges, consider normally foreseeable. For further information write to: 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. In the circuit, When button is not pressed: The series are digital logic integrated circuits.

As shown in diagram, we have a transistor forming a NOT gate. Hitachi Semiconductor America Inc. Products and product specifications may be subject to change without notice. The chip has six gates which do NOT operation. Confirm that you have. Hex Inverters with Open Collector Outputs.

Here are datxsheet cases where 74LS04 is 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 incorporating Hitachi product does not cause bodily injury, fire or other consequential datasheeh due to operation of the Hitachi product.

The description for each pin is given below. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly.
