Technological growth in electronics very fast, if last some years, electronics circuit use vacuous tube component, diskrit component, like dioda, transistor, hence now have is other, that is using digital system, and in digital equipments presentation of information or data represent expressed numbers formation in the form of is digital ( logic circuit). There are some elementary circuit from digital logic, that is NOTE gate, AND gate, OR gate, NAND gate, NOR gate, XOR gate and XNOR gate. This experiment gate logic circuit aim to so that student know just something which the included in logic gate, and know truth table of from each logic gate.4/13/201224/13/20122II. Theory

On the introduction of Logic GateLogic gates or logic gate is an entity in electronics and mathematics Boolean that turns one or more logic inputs to a logic output signal. Logic gate is mainly implemented electronically using diodes or transistors, but can also be built using the arrangement of components that utilize the properties of electromagnetic (relay), fluids, optical or even mechanical.4/13/201234/13/20123In the digital circuit, there is some logic gates are used, such as:

Inverter gate (NOT)An inverter (inverting) is a gate with an input signal and an output signal where the output state is always opposite to the input state. INV logic gates on the other names Datasheet TTL IC 7404.

AND gateAND gate has two or more than two input signals, but only one output signal. The AND gate, to produce a high output signal then all input signals must be of high value. AND logic gate at the other names Datasheet IC TTL 7408.

4/13/20125

OR gateOR gate will provide a high output signal if one or all of the input signal value, so it can be said that the OR gate output signal is low only if all input signals of low value. OR logic gate at the other names Datasheet IC TTL 7432.

4/13/20126NAND gateNAND gate is a NOT-AND, or an AND function is reversed. In other words that the NAND gate will produce a low output signal when all the input signal is of high value. NAND logic gates at the other names Datasheet IC TTL 7400.

4/13/20127

NOR gateNOR gate is a NOT-OR, or an OR function is reversed so that it can be said that the NOR gate will produce a high output signal when all of the input signal is of low value. NOR logic gate at the other names Datasheet IC TTL 7402.

4/13/20128

XOR gateXOR gate will produce a low output signal when all of the input signal is low-value or high value any input or in other words that the XOR will produce a low output signal when the input signal value at all. XOR logic gate at the other names Datasheet IC TTL 7486.

4/13/20129

X-NOR gateX-NOR gate will produce a high output signal when all input signals are equal (the opposite of the XOR gate). X-NOR logic gate on a TTL IC Datasheet 74 266 other names.

Output test from each logic gate with input variation from the circuit and write its output.comparing output with truth tables of is each gate.4/13/201212IV. DATA ANALYSIS.

IC NOT7404 gate was composed of an inverter are interconnected.IC NAND7400 gate was composed of NOT and AND gates are interconnected.IC NOR7402 gate was composed of NOT and OR gates are interconnected.IC XOR7486 gate was composed of interconnected XOR gate.IC gate XNOR4077 Executive was made up of gates, NOT and OR are interconnected.OR7432 gate IC was composed of OR gates are interconnected.4/13/2012134/13/201213V. CONCLUSIONIC consist of some logic gate.Logic gate can be used to create many IC.

Practice is more conducive again.

Student expected to be more focused in the following experiments and more orderly in making the circuit to be easily understood.4/13/2012154/13/201215VII. BIBLIOGRAPHY
