Hitachi Asia Hong Kong Ltd. In the circuit, When button is not pressed: TL — Programmable Reference Voltage. No one is permitted 74ls004 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. Even datasheeet 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.


Even within the guaranteed ranges, consider normally foreseeable. Confirm that you have.

Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. Datashwet publications Share Embed Add to favorites Comments. We can use one or all six of these gates depending on requirement.

74LS04 Hoja de datos ( Datasheet PDF ) – Hex Inverters(with Open Collector Outputs)

Design your application so that the product is used within the ranges guaranteed by Hitachi particularly. The device should not be operated at these limits. Because base current is zero the transistor will be in OFF state. For further information write to: These NOT gates perform Inverting function.

Datasheet – 74LS04

Here are few cases where 74LS04 is used. Now let us take a single gate of the six and connect it as shown in circuit fatasheet. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without.

The chip has six gates which do NOT operation. Under OFF sate the total supply voltage appears across the transistor. As shown in diagram, we have a transistor forming a NOT gate. Tokyo 03 Fax: When button is pressed: The internal connection of gates can be given as below. The LED is connected to know the output status.


Life support devices or systems are devices or systems which, a are intended for surgical implant into the body, or b support or sustain life, and c whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury to the user. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.

The series are digital logic integrated circuits.

Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. Choose the appropriate package depending on requirement.

Products and product specifications may be subject to change without notice. Not more than one output should be shorted at a time. We have six of these gates in 74LS04 chip.

When you want TTL outputs. Voltage appears at base of transistor and current flows through it.
