PDF 74LS04 Datasheet ( Hoja de datos )

Life support devices or systems are devices or systems which, a are intended for surgical datsaheet 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 datxsheet injury to the user.

Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. Now let us take a single gate of the six and connect it as shown in circuit diagram. When button is pressed: If we draw truth table based on above cases, we will have. Hitachi bears no responsibility for failure or damage when used beyond the datashedt ranges. Products and product specifications may be subject to change without notice.

Here are few cases where 74LS04 is used. We can use one or all six of these gates depending on requirement. As shown in diagram, we have a transistor forming a NOT gate. Recommended Operating Conditions Electrical Characteristics over recommended operating free air temperature range unless otherwise noted Note 2: Hex Inverters with Open Collector 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.

No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without written approval from Hitachi. The device should not be operated at these limits. The chip is basically used where a logic inverter is needed.

Because base current is zero the transistor will be in OFF state. Under OFF sate the total supply voltage appears across the transistor. Voltage appears at base of transistor and current flows through it.

Devices also available in Tape and Reel. For further information write to: 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 parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.

Design your application so that the product is used within the ranges guaranteed by Hitachi particularly. Confirm that you have. Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor.
