Kazikazahn The description for each pin is given below. Hitachi Asia Hong Kong Ltd. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. Input dataeheet is 1A which is connected to button.

We have six of these gates in 74LS04 chip. 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.

Because base current is zero the transistor will be in OFF state. This product is not designed to be radiation resistant. When button is pressed: Recommended Dqtasheet Conditions Electrical Characteristics over recommended operating free air temperature range unless otherwise noted Note 2: For further information write to: The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.

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.

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 74ps04 with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury to the user.

Because base current is present the transistor will turn ON. Confirm that you have received the latest product standards or specifications before final design, purchase or use. Choose the appropriate package depending on requirement. Inverter Gates in this chip provide output which is negated logic input. Output 1Y is connected to LED through a resistor. Now let us take a single gate of the six and connect it as shown in circuit diagram.

These NOT gates perform Inverting function. In the datashfet, When button is not pressed: The gates in this chip datasneet TTL logic outputs which are a must in some applications.

The chip is basically used where a logic inverter is needed. Devices also available in Tape and Reel. When you want TTL outputs. 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.

Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. Hitachi Semiconductor America Inc. The series are digital logic integrated circuits.

Under such case the output datazheet here will also be LOW, since output is nothing but voltage across transistor. Voltage appears at base of transistor and current flows through it. The device should not be operated at these limits. Hex Inverters with Open Collector Outputs.

No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without written approval from Hitachi. TL — Programmable Reference Voltage. The chip has six gates which do NOT operation. Current through base of transistor will be zero. Related publications Share Embed Add to favorites Comments. If we draw truth table based on above cases, we will have.

We can use one or all six of these gates depending on requirement. Hitachi makes every attempt to ensure that its products are of high quality and reliability. Design your application so that the product is used within dxtasheet ranges guaranteed by Hitachi particularly.

Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. The internal connection of gates can be given as below. Related Posts.
