The device should not be operated at these limits. Products and product specifications may be subject to change without notice. Confirm that you have. Hitachi Semiconductor America Inc. This datasheet has been downloaded from: If we draw truth table based on above cases, we will have. Now let us take a single gate of the six and connect it as shown in circuit diagram. When button is pressed: Hitachi bears no responsibility for failure or damage when used.

Confirm that you have received the latest product standards or specifications before final design, purchase or use. Tun-Hwa North Road, Taipei Here are few cases where 74LS04 is used. Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero.

The chip is basically used where a logic inverter is needed. Even within the guaranteed ranges, consider normally foreseeable. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. When you want TTL outputs.

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

As shown in diagram, we have a transistor forming a NOT gate.

Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. TL — Programmable Reference Voltage. For further information write to: Under OFF sate the total supply voltage appears across the transistor.

The description for each pin is given below. The chip has six gates which do NOT operation. 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.

Choose the appropriate package depending on requirement. Voltage appears at base of transistor and current flows through it. 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 use provided in the labeling, can be reasonably expected to result in a significant injury to the user.
