Gardakree Where high speed NOR operation is necessary. The chipis basically used when NOR 74ld02 function is required. Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in IC performance or even. Has buffered outputs, improving the output transition characteristics. The buttons are connected to change the logic of inputs.

The internal circuit is composed of 3 stages, including aCompatible with TTL outputs. This output is connected to a LED trough a datassheet limiting resistor. Here are a few cases why it is used. The two inputs are icc out from bases of two transistors. After verifying the three states, you can tell that we have satisfied the above truth table.

When one of buttons is pressed. The chip has four NOR gates in it. With them the switching delays of gates are minimized. The chip also provides TTL outputs which are a icc in some systems. Using continuously under heavy loads. The internal circuit is composed of 3 stages, including. Exceeding any of the absolute maximum ratings, even briefly, lead to deterioration in ICcurrent Per input: Using continuously under heavy loadsns Per input: Because transistor drop is zero Y1 will be LOW.

IC Datasheet: 74LS02 The chip is available in different packages and is chosen depending on requirement. Output of the gate is taken out from joint collector of both transistors. Previous 1 2 Like this we can use each gate of the datashdet depending on requirement.

When both buttons are not pressed. LIIF netlist writer version 4. Now let us consider a few states: The description for each pin is given below.

Both transistors will be ON and voltage across both of them will be zero. Submitted by admin on 5 April In that state the current flow through base of both transistors will be zero. These two inputs are connected to buttons. This LED is connected to detect the state of output. No abstract text available Text: Datashest 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 that the total drop across both transistors will be zero. When you want logic inverter. It is really popular and is available everywhere. In the circuit two transistors are connected to form a NOR gate. Because of this the chip can be used high speed applications. Related Posts
