Speed: Speed of a logic circuit is determined by the time between the application of input and change in the output of the circuit.įan-in: It determines the number of inputs the logic gate can handle.įan-out: Determines the number of circuits that a gate can drive. The main characteristics of Logic families include: This 74LS08 AND Gate IC can be operated with any TTL device without using any interface device.Logic Families indicate the type of logic circuit used in the IC. The size of this IC is very small and available in different packages so that it can be adaptable in any small size device. As compared to a single handmade AND gate, this IC cost is very less. Thus, this is all about an overview of a 74LS08 AND Gate IC datasheet. It is very famous & accessible everywhere. This AND gate IC is very cheap used for AND gate logic operation.So this IC can be utilized for AND operations with high speed. These logic gates are designed with Schottky transistors for making the logic gate switching delays less.This IC is also very useful where AND gate with high-speed operation is necessary.This IC includes 4 AND gates where a single gate or all logic gates are used simultaneously. This IC is mainly used wherever the logic operation of AND gate is required.It is used in different devices of servers, ALU, digital electronics, memory units, networking devices.This IC is mainly to achieve general-purpose AND gate logic.Here the output will not depend on the type of AND gate but the output will be always according to the truth table of AND gate which is given below. In other situations, if one of the input pins is LOW within the circuit next the o/p will be LOW due to the current supply from the transistors. Once the input signal is HIGH then-current supplies throughout this transistor & complete voltages will be obtained on the o/p pin. The inputs allow the flow of current from the two transistors. AND Gate based on Transistorsįor both the transistors, the two inputs are given to the base terminal. The power is given to the first transistor’s collector terminal & the output can be obtained on the emitter terminal of the next transistor. In IC 74LS08 AND logic gate, both the transistors are connected in series. The following circuit includes two transistors which are used as a switch to modify the condition of output for different inputs. Here, the transistor-based logic AND gate circuit is shown below. Generally, AND logic gate includes 3 types of combinations where each combination includes similar outputs on precise inputs. To understand 74LS08 AND gate IC, first, we have to recognize how a single AND logic gate works.
