Under ON sate the total supply voltage appears across the resistor and voltage across transistor will be zero. For further information write to: TL — Programmable Reference Voltage.

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. Submitted by admin on 4 April Copyright ‘ Hitachi, Ltd. Recommended Operating Conditions Electrical Characteristics over recommended operating free air temperature range unless otherwise noted Note 2: 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.


If we draw truth table based on above cases, we will have. Because base current is present the transistor will turn ON. Hitachi makes every attempt to ensure that its products are of high quality and reliability. Under such case the output 1Y here will be HIGH, since output is nothing but voltage across transistor. Devices also available in Tape and Reel. These NOT gates perform Inverting function.

74LS04 Pinout, Features, Equivalent, Examples & Datasheet

Tokyo datashete Fax: No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without written approval from Hitachi.

Voltage appears at base of transistor and current flows through it. We have six of these gates in 74LS04 chip. Confirm that you have. Output 1Y is connected to LED through a resistor. The device should not be operated at these limits. We can use one or all six of these gates depending on requirement.


Not more than one output should be shorted at a time.

The description for each pin is given below. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. Current through base of transistor will be zero. Even within the guaranteed ranges, consider normally foreseeable.

Under OFF sate the total supply voltage appears across the transistor. As shown in diagram, we have a transistor forming a NOT gate.
