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 74lw04 use provided in the labeling, can be reasonably expected to result in a significant injury to the user.

Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. Products and product specifications may be subject to change without notice. The chip datssheet basically used where a logic inverter is needed. The device should not be operated at these limits.

If we draw truth table based on above cases, we will have. Copyright ‘ Hitachi, Ltd. Voltage appears at base of transistor and current flows through it. Recommended Operating Conditions Electrical Characteristics over recommended operating free air temperature range unless otherwise noted Note 2: Confirm that you datazheet received the latest product standards or specifications before final design, purchase or use.

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. Hex Inverters with Open Collector Outputs. The description for each pin is given below.

In the circuit, When button is not pressed: Because base current is present the transistor will turn ON. Tokyo 03 Fax: Inverter Gates in this chip provide satasheet which is negated logic input.

We can use 74ks04 or all six of these gates depending on requirement. Hitachi bears no responsibility for failure or damage when used. 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.

The internal connection of gates can be given as below. Related publications Share Embed Add to favorites Comments. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without.

The gates in this chip provide TTL logic outputs which are a must in some applications. Because datzsheet current is zero the transistor will be in 774ls04 state.

Here are few cases where 74LS04 is used. Hitachi Semiconductor America Inc. Devices also available in Tape and Reel. Hitachi Asia Hong Kong Ltd. TL — Programmable Reference Voltage. The LED is connected to know the output status.

Hitachi makes every attempt to ensure that its products are of high quality and reliability. Current through base of transistor will be zero.

74LS04 NOT Gate IC | IC Datasheet

Choose the appropriate package depending on requirement. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly.

The chip has six gates which do NOT operation. Datxsheet such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor.

Datasheet – 74LS04

This product is not designed to be radiation resistant. Input here is 1A which is connected to button. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly for maximum rating, operating supply voltage range, heat datashheet characteristics, installation conditions and other characteristics. Tun-Hwa North Road, Datashwet Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero.

We have six of these gates in 74LS04 chip. Under OFF sate the total supply voltage appears across the transistor. Not more than one output should be shorted at a time.

This datasheet has been downloaded from: As shown in diagram, we have a transistor forming a NOT gate. These NOT gates perform Inverting function. Submitted by admin on 4 April Now let us take a single gate of the six and connect it as shown in circuit diagram.
