Hitachi Asia Hong Kong Ltd. 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 datashret 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 chip is basically used where a logic inverter is needed.

Devices also available in Tape and Reel. Because base current is present the transistor will turn ON. Voltage appears at base of transistor and current flows through it.

Choose the appropriate package depending on requirement. Because base current is zero the transistor will be in OFF state. Recommended Operating Conditions Electrical Characteristics over recommended operating free air temperature range unless otherwise noted Note 2: Here are few cases where 74LS04 is used. Tokyo 03 Fax: 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.


The internal connection of gates can dxtasheet given as below. The gates in this chip provide TTL logic outputs which are a must in some applications. We can use one or all six of these gates depending on requirement. Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero.

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

Hitachi Semiconductor America Inc.

The series are digital logic integrated circuits. In the circuit, When button is not pressed: When you want TTL outputs. Hitachi makes every attempt to ensure that its products are of high quality and reliability. Under such case datasbeet output 1Y here will also be LOW, since output is nothing but voltage across transistor. The description for each pin is given below.

Confirm that you have received the latest product standards or specifications before final design, purchase or use. Current through base of transistor will datashset zero. As shown in diagram, we have a transistor forming a NOT gate. Not more than one output should be shorted at a time. 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. Output 1Y is connected to LED through a resistor. 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.

We have six of these gates in 74LS04 chip. When button is 74ls40 Hex Inverters with Open Collector Outputs. Submitted by admin on 4 April Inverter Gates in this chip provide output which is negated logic input. The LED is connected to know 74ls0 output status. This product is not designed to be radiation resistant.
