74LS04 Pinout, Features, Equivalent, Examples & Datasheet
Current through base of transistor will be zero. Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor.
For further information write to: When button is pressed: We can use datashset or all six of these gates depending on requirement.
Voltage appears at base of transistor and current flows through it. Because base current is present the transistor will turn ON. Now let us take a single gate of the six and connect it datasehet shown in circuit diagram. Here are few cases where 74LS04 is used. Datxsheet LED is connected to know the output status. 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.

Submitted by admin on 4 April Input here is 1A which is connected to button. Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero.
Hitachi makes every attempt to ensure that its products are of high quality and reliability. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges.
Tokyo 03 Fax: No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without. Under OFF sate the total supply voltage appears across the transistor.
Datasheeet device should not be operated at these limits.
These NOT gates perform Inverting function. The internal connection of gates can be given as below.
The chip is basically used where a logic inverter is needed. The chip has six gates which do NOT operation.
No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without written approval from Hitachi.
Inverter Gates in this chip provide output which is negated logic input. If we draw truth table based on above cases, we will have.
Datasheet – 74LS04
The description for each pin is given below. We have six of these gates in 74LS04 chip. This product is not designed to be radiation resistant. 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.
In the circuit, When button is not pressed: Devices also available in Tape and Reel. Recommended Operating Conditions Electrical Characteristics over recommended operating free air temperature range unless otherwise noted Note 2: TL — Programmable Reference Voltage. Hitachi Semiconductor America Inc. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly. Confirm that you have.
As shown in diagram, we have a transistor forming a NOT gate. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor.
