Even within the guaranteed ranges, consider normally foreseeable. Output of the gate is taken out from joint collector of both transistors.

74LS02 NOR Gate IC Pinout, Features, Equivalents, Circuit & Datasheet

The chipis basically used when NOR logic function is required. We can use one or all gates. The chip has four NOR gates in it. The description for each pin is datashert below.

The chip is available in different packages and is chosen depending on requirement. In that state the current flow through base of both transistors will be zero.

Now let us consider a few states: In the circuit two transistors are connected to form a NOR gate. Here datazheet a few cases why it is used. This output is connected to a LED trough a current limiting resistor. With that the total drop across both transistors will be zero. TL — Programmable Reference Voltage. It is really popular and is available everywhere.

Because of this the chip can be used high speed applications. Hitachi Semiconductor America Inc.

Tun-Hwa North Road, Taipei Hitachi Asia Hong Kong Ltd. The four NOR gates in the chip mentioned earlier are connected internally as shown below.

VCC-Connected to positive voltage to provide power to all four gates. With them the switching delays of gates are minimized.

Because transistor drop is zero Y1 will be LOW. For further information write to: 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.

Confirm that you have. Copyright ‘ Hitachi, Ltd. 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.

When one of buttons is pressed.

Tokyo 03 Fax: Both transistors will be ON and voltage across both of them will be zero. Like this we can use each gate of the datashret depending on requirement. Submitted by admin on 5 April
