## Which IC is use for Triple 3-input NOR gate?

The 74HC27; 74HCT27 is a triple 3-input NOR gate. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

What is the IC number of 3-input AND gate?

74LS11 Triple 3-Input AND Gate IC (7411 IC) DIP-14 Package.

What is 3-input NOR gate?

description. These devices contain three independent 3-input positive-NOR gates. They perform the Boolean functions Y = A • B • C or Y = A + B + C in positive logic. The SN54ALS27A and SN54AS27 are characterized for operation over the full military temperature range of −55°C to 125°C.

### What is NOR gate IC number?

Quad two-input NAND gate (four NAND gates) 7402. Quad two-input NOR gate (four NOR gates) 7404.

What is the truth table of NOR gate?

The NOR gate is a digital logic gate that implements logical NOR – it behaves according to the truth table to the right. A HIGH output (1) results if both the inputs to the gate are LOW (0); if one or both input is HIGH (1), a LOW output (0) results. NOR is the result of the negation of the OR operator.

Is nor a universal gate?

A universal gate is a gate which can implement any Boolean function without need to use any other gate type. The NAND and NOR gates are universal gates.

#### Can or gate have 3 inputs?

Like the AND gate, the OR function can have any number of individual inputs. However, commercial available OR gates are available in 2, 3, or 4 inputs types. Additional inputs will require gates to be cascaded together for example.

How many NOR gates are required for AND gate?

AND: You need three NOR gates to create an AND gate. The first two are configured as NOT gates, so they invert the inputs. Then the third NOR gate produces a HIGH output if both of the original inputs are HIGH. NAND: It takes four NOR gates to create a NAND gate.

What is the difference between OR gate and NOR gate?

NOR Logic Gate Symbol and Truth Table. This is basically a NOT-OR gate which is equal to an OR gate followed by a NOT gate. The outputs of all NOR gates are false if any of the inputs are true. The symbol is OR gate with small circle on the output.

## What is the symbol of NOR gate?

The Boolean expression for a logic NOR gate is denoted by a plus sign, ( + ) with a line or Overline, ( ‾‾ ) over the expression to signify the NOT or logical negation of the NOR gate giving us the Boolean expression of: A+B = Q.

Which IC is required for NOR gate?

74LS02 is a LOGIC GATE IC and member of 74XXYY IC series which are logic gates. There are four NOR gates in the IC and each gate has two inputs, hence the name QUADRUPLE TWO INPUT NOR GATE….Pin configuration.

Pin Number Description
NORGATE 1
2 1A-INPUT1 of GATE 1
3 1B-INPUT2 of GATE 1
1 1Y-OUTPUT of GATE1

What is the IC number of the NOR gate?

The IC number of NOR Gate is 7402. Symbol of NOR gate Truth table of NOR gate If one of the inputs in the NOR gate is high then the output of the NOR gate is low.

### How big is a 3 input positive NOR gate?

Single 3-Input Positive-NOR Gate See mechanical drawings for dimensions. DBV PACKAGE (TOP VIEW) GND2 5VCC B 3 4 Y A 16 C DCK PACKAGE (TOP VIEW) B3 4 GND2 Y 5 A 1 VCC

Is the Boolean function the same for the 3-input XNOR gate?

The Boolean function is same for the 3- input XNOR gate is 3-Input Ex-NOR gate logic symbol Truth table For Exclusive NOR gates, we can have the HIGH input when even numbers of inputs are at HIGH level. So the 3-input XNOR gate is called as “Even functioned OR gate”.The truth table and logic symbol for 3-input XNOR gate is given below.

Which is true about the Exclusive NOR gate?

3-Input Ex-NOR gate logic symbol Truth table For Exclusive NOR gates, we can have the HIGH input when even numbers of inputs are at HIGH level. So the 3-input XNOR gate is called as “Even functioned OR gate”.The truth table and logic symbol for 3-input XNOR gate is given below.
