Datasheet – 74LS04

Inverter Gates in this chip provide output which is negated logic input. Tokyo 03 Fax: When you want TTL outputs. In the circuit, When button is not pressed: Even within the guaranteed ranges, consider normally foreseeable.

Recommended Operating Conditions Electrical Characteristics over recommended operating free air temperature range unless otherwise noted Note 2: Voltage appears at base of transistor and current flows through it.

Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. Because base current is present the transistor will turn ON.


74ls044 OFF sate the total supply voltage appears across the transistor. Current through base of transistor will be zero. Input here is 1A which is connected to button. Hitachi bears no responsibility for failure or damage when used. Confirm that you have.

These NOT gates perform Inverting function. 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 dataeheet provided in the labeling, can be reasonably expected to result in a significant injury to the user. The series are digital logic integrated circuits.

The chip has six gates which do NOT operation.

Here are few cases where 74LS04 is used. Tun-Hwa North Road, Taipei TL — Programmable Reference Voltage. Hitachi Asia Hong Kong Ltd. Even within the guaranteed ranges, consider normally foreseeable failure rates or datashet 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.


When button is pressed: The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. Hex Inverters with Open Collector Outputs. Confirm that you have received the latest product standards or specifications before final design, purchase or use.

The gates in this chip provide TTL logic outputs which are datasneet must in some applications. The internal connection of gates can be given as below.

Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor. Submitted by admin on 4 April Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero.

A critical component in any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness.
