This output is connected to a LED trough a current limiting resistor. Even within the guaranteed ranges, consider normally foreseeable. Products and product specifications may be subject to change without notice. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without.

Now let us consider a few states: Hitachi Semiconductor America Inc. It is really popular and is available everywhere.

Tun-Hwa North Road, Taipei The description for each pin is given below. This product is not designed to be radiation resistant. Because of this the chip can be used high speed applications. Because transistor drop is zero Y1 will be LOW. The four NOR gates in the chip mentioned earlier are connected internally as shown below.

fatasheet The chip has four NOR gates in it. Here are a few cases why it is used. For realizing the above truth table let us take simplified NOR gate and have it connected as shown below.

The chip also provides TTL outputs which are a must in some systems. In that state the current flow through base of both transistors will be zero.

Confirm that you have received the latest product standards or specifications before final design, purchase or use. Output of the gate is taken out from joint collector of both transistors.

When both buttons are not pressed. The chip is available in different packages and is chosen depending on requirement. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly.
