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.

Even within the guaranteed ranges, consider normally foreseeable. Input here is 1A which is connected to button. Now let us take a single gate of the six and connect it as shown in circuit diagram. 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.
Hitachi Asia Hong Kong Ltd.
Hex Inverters with Open Collector Outputs. Inverter Gates in this chip provide output which is negated logic input. TL — Programmable Reference Voltage. We have six of these gates in 74LS04 chip. Here are few cases where 74LS04 is used. Tokyo 03 Fax: In datasheett circuit, When button is not pressed: Products and product specifications may be subject to change without notice.
The description for each pin is given below. The chip is basically used where a logic inverter is needed. If we draw truth table based on above cases, we dataaheet have. When button is pressed: Choose the appropriate package depending on requirement.
Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. Submitted by admin on 4 April Voltage appears at base of transistor and current flows through it.
When you want TTL outputs. We datsaheet use one or all six of these gates depending on requirement. Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero.
Current through base of transistor will be zero. Copyright ‘ Hitachi, Ltd. The LED is connected to know the output status.
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. 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.
Hitachi makes every attempt to ensure that its products are of high quality and reliability. Hitachi Semiconductor Datashheet Inc.
Tun-Hwa North Road, Taipei The chip has six gates which do NOT operation. For further information write to: As shown in diagram, we have a transistor forming a NOT gate.
Confirm that you have. The series are digital logic integrated circuits.
