Now let us take a single gate of the six and connect it as shown in circuit diagram.

Input here is 1A datashedt is connected to button. We can use one or all six of these gates depending on requirement. Hitachi bears no responsibility for failure or damage when used.

These NOT gates perform Inverting function. Current through base of transistor will be zero.

The chip has six gates which do NOT operation. For further information write to: Design your application so that the product is used within the ranges guaranteed by Hitachi particularly.

Hitachi Semiconductor America Inc. Confirm that you have. Under ON dataasheet the total supply voltage appears across the resistor and voltage across transistor will be zero.

Because base current is zero the transistor will be in OFF state. Output 1Y is connected to LED through a resistor. Hex Inverters with Open Collector Outputs. The series are digital logic integrated circuits. Under OFF sate the total supply voltage appears across the transistor. Design your application so that the 74le04 is used within the ranges guaranteed by Hitachi particularly for maximum rating, operating supply voltage range, heat radiation characteristics, installation conditions and other characteristics.

We have six of these gates in 74LS04 chip. In the circuit, When button is not pressed: Copyright ‘ Hitachi, Ltd. The description for each pin is given below. Choose the appropriate package depending on requirement.

TL — Programmable Reference Voltage. Products and product specifications may be subject to change without notice. Tokyo 03 Fax: When you want TTL outputs.
