74LS04 DATASHEET PDF

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.

Confirm that you have.

The description for each pin is given below. TL — Programmable Reference Voltage. Under OFF sate the total supply voltage appears across the transistor. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without written approval from Hitachi. Tun-Hwa North Road, Taipei Current through base of transistor will be zero.

Input here is 1A which is connected to button. Hitachi Semiconductor America Inc. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly.

Because base current is zero the transistor will be in OFF state. Here are few cases where 74LS04 is used. Even within the guaranteed ranges, consider normally foreseeable. Output 1Y is connected to LED through a resistor. Copyright datashee Hitachi, Ltd. In the circuit, When button is not pressed: As shown in diagram, we have a transistor forming a NOT gate.

Choose the appropriate package depending on requirement. Hitachi Asia Hong Kong Ltd. Products and product specifications may be subject to change without notice. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. Voltage appears at base of transistor and current flows through it. Inverter Gates in this chip provide output which is negated logic input.

These NOT gates perform Inverting function. When you want TTL outputs. Hex Inverters with Open Collector Outputs. 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.

Hitachi bears no responsibility for failure or damage when used. We have six of these gates in 74LS04 chip. The LED is connected to know the output status. Hitachi makes every attempt to ensure that its products are of high quality and reliability.

Under such case the output 1Y here will also be LOW, since output is nothing but voltage across transistor. Submitted by admin on 4 April The gates in this chip provide TTL logic outputs which are a must in some applications. The chip has six gates which do NOT operation. 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 present the transistor will turn ON. Hitachi bears no responsibility for failure or damage datashee used beyond the guaranteed ranges. Now let us take a single gate of the six and connect it as shown in circuit diagram. The chip is basically used where a logic inverter is needed. When button is pressed: We can use one or all six of these gates depending on requirement.

Tokyo 03 Fax: No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without. The series are digital logic integrated circuits. Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. If we draw truth table based on above cases, we will have.
