The design look great though! So, if we connect the NOT gate at both inputs of a NOR gate, we will get an AND gate equivalent. the output is given below. The output of OR gate is HIGH only if a one of the inputs are HIGH Even if one input is LOW, the output will HIGH. NOR Gate is Compliment of OR. Just like an OR gate, a NOR gate may have any number of input probes but only one output probe. Lessons In Electric Circuits, Volume 4, chapter 3: “Logic Gates” Lessons In Electric Circuits, Volume 4, chapter 10: “Multivibrators” The 4001 integrated circuit is a CMOS quad NOR gate, identical in input, output, and power supply pin assignments to the 4011 quad NAND gate. IC 74138 is a Logical Decoder IC. NAND gate is a logic gate Which can have two or more inputs.But there is only one output. 0 which you can find out from the truth table of the NOR gate. Also, we know that all complex binary operations can be realized by using these three basic operations. The output will be high only if both transistors are at cut-off state. Logic equation is: Digital IC for NOR: IC 7402. 1. In the same way as NAND is a combination of "NOT plus AND", NOR is blend of "NOT plus OR". HIGH. Logic equation is:X = A ⊕ B Digital IC for XNOR : IC: 74266. 1 at the input the output that we get will be binary low i.e. I’m not sure if this is a format issue or something to do with internet browser compatibility but I figured I’d post to let you know. TRUTH TABLE; INPUT Write out a logical expression for the output for each circuit connection in your experiment. Quad 2-Input AND Gates with Open-Collector Outputs, 7409 datasheet, 7409 circuit, 7409 data sheet : NSC, alldatasheet, datasheet, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes, triacs, and other semiconductors. LOW. HIGH. Logic equation is: X = A . Logic equation is: X = X Digital IC for NOT: IC 7404. What have you done with this place to make it so amazing?! The output of NAND gate is HIGH only if Both inputs are same. The two inputs are driven out from bases of two transistors. In inverter is Always opposite of input. or VIL per Truth Table VOL Output LOW Voltage 54, 74 0.25 0.4 V IOL = 4.0 mA VCC = VCC MIN, Output LOW Voltage VIN =VIL or VIH 74 0.35 0.5 V IOL = 8.0 mA = V or V per Truth Table IIH Input HIGH Current 20 µA VCC = MAX, VIN = 2.7 V Input HIGH Current 0.1 mA VCC = MAX, VIN = 7.0 V IIL Input LOW Current –0.4 mA VCC = MAX, VIN = 0.4 V Either transistor must be cut-off “OFF” for an output at Q. COMPONENTS REQUIRED:- Logic gates (IC) trainer kit. Logic NOR gate can be used to construct EX-OR gates and some other real time applications. Your email address will not be published. Experiment No.1 Aim: To study and verify the Truth Tables of AND, OR, NOT, NAND, NOR, EXOR logic gates Components: IC 7400, 7402, 7404,7408,7432,7486 Hope you get the issue solved soon. below shows the circuit symbol, Boolean function, and truth. Vary the inputs and make the truth table 2. NAND GATE CIRCUIT DIAGRAM. we observe that in every logic gate, the input pins are (1,2), (4,5), (9,10), (12,13) and output pins are (3), (6), (8), (11) but in case of 7402 nor gate, the input and output pins are reversed i.e. LOW. 7402 Quad 2-input NOR Gate In the next tutorial about Digital Logic Gates , we will look at the digital logic Exclusive-OR gate known commonly as the Ex-OR Gate function as used in both TTL and CMOS logic circuits as well as its Boolean Algebra definition and truth tables. Back to top. If inputs of two inputs OR gate are 1, then the output is 1 and when both inputs of two inputs OR gate is 0, the output is 0. If we can prove that AND, OR, and NOT operations can be realized by using only the NOR gate, then we can easily say that all binary operations can be realized by using only NOR gates. Arvind Ahir the output is given below. The truth table of NAND gate is given as, Input1. A diagram of the chip appears here. B.Tech CSE : CT INSTITUTE OF b. Pin „GND‟ on an I.C is to be connected to the power supply ground. NAND is Compliment of AND .The output of NAND gate is HIGH only if one inputs are HIGH or both input being LOW.if both input is HIGH the output is LOW, the output is given below. Its output will be in low state if any of its input is in high state. Description 7402 Quad 2-input NOR gate. B +… It is seen from the Fig that each gate has one or two binary inputs, A and B, and one binary output, C. The small circle on the output of the circuit symbols designates the logic complement. IC 7402 comes up in multiple packages with 14 pins and 2 inputs 4-NOR gates. THEORY: A gate can be extended to have multiple inputs if the binary operation it represents is commutative and associative. 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. A few of the most popular include: IC 7402 contains four two inputs NOR gates. NOR gate means “not an OR gate” hence the output of this logic gate is just the reverse of that of an OR gate. Learn Technology, Make Stuff ,Spread to other so they can Learn Too. We can verify the operation by the truth tables and also by glowing of LED. AND gate is a logic gate Which can have two or more inputs.But there is only one output. It may be any one of the following chips: AND, NAND, OR, NOR, XOR, XNOR. Logic equation is: X = A + B Digital IC for OR: IC 7432. HIGH. if both input is different the output is LOW, the output will below. Keep up the good work. IC 7402(NOR), IC 7400(NAND), 7404(NOT), 7408(AND), 7432(OR), KL 33002, power supply, connecting wires and Breadboard etc. IC 7432 Pin diagram, circuit design, Datasheet, Application Reviewed by ETechnoG on 1/31/2019 Rating: 5 Given a Truth table to derive the Boolean expressions and build the logic circuit to realize it. Prelab: 1. The truth table of 3 –input NOR gate is given below. Operation of the NOR gate is verified from the truth table. Which can have two or more inputs.But there is only one output. It may be due to not updated of Opera Browser. The logical equivalent circuit will be as shown below. List of Apps you Don’t Install in Android Phone. In the circuit when both A and B are given +5 V, base of the both transistors gets quite a high potential to make the transistors ‘ON’. B Digital IC for AND: IC 7408. HIGH. That’s my advice pal. List of Network Monitoring Tools and Software, LOGICS-GATES-OR-AND-XOR-NOT-NOR-NAND-XNOR. So any even much complex binary operation can be realized by using only a NOR gate hence it is quite justified to cal a NOR gate as a universal logic gate. In IC all gates come up with buffered output and it has the ability to provide noise immunity to drive LS-TTL Loads.
