Note The ”Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaran- teed The device should not be operated at. µA. VCC = MAX, VIN = V. IIH. Input HIGH Current. mA. VCC = MAX, VIN = V. IIL. Input LOW Current. – mA. VCC = MAX, VIN = V. IOS. 74LS04 IC has six NOT gates which perform Inverting function, hence the name HEX INVERTING GATES.

The chip has six gates which do NOT operation. We have six of these gates in 74LS04 chip. TL — Programmable Reference Voltage. 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.
Devices also available in Tape and Reel. Copyright ‘ Hitachi, Ltd. We can use one or all six of these gates depending on requirement. The internal connection of gates can be given as below.
Choose the appropriate package depending on requirement. The chip is basically used where a logic inverter is needed. These NOT gates perform Inverting function. Even within the guaranteed ranges, consider normally foreseeable. Not more than one output should be shorted at a time.
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 dataxheet the life support device or system, or to affect its safety or effectiveness. The device should not be operated at these limits. The LED is connected to know the output status. Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero.
Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor. Hitachi bears no responsibility for failure or damage when used. Hex Inverters with Open Collector Outputs. The series are digital logic integrated circuits.
Input here is 1A which is connected to button. Tun-Hwa North Road, Taipei Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. Current through base of transistor will be zero. For further information write to: This product is not designed to be radiation resistant.
Output 1Y is connected to LED through a resistor. Products and product specifications may be subject to change without notice. Because base current is present the transistor will turn ON.
Hitachi Asia Hong Kong Ltd. Now let us take a single gate of the six and connect it as shown in circuit diagram.

Recommended Operating Conditions Electrical Characteristics over recommended operating free air temperature range unless otherwise noted Note 2: Confirm that datasheeg have received the latest product standards or specifications before final design, purchase or use.
Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. Confirm that you have. If we draw truth table based on above cases, we will have. The description for each pin is given below.
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.
As shown in diagram, we have a transistor forming a NOT gate. 74ls044 appears at base of transistor and current flows through it. Hitachi Semiconductor America Inc.
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.
Submitted by admin on 4 April When button is pressed: Inverter Gates in this chip provide output which is negated logic input. Under OFF sate the total supply voltage appears across the transistor. Because base current is zero the transistor will be in OFF state.
When you want TTL outputs.
