Nand Gate Pencil Box

Department of Technology and the Arts Glenforest Secondary School data processor Engineering Technology TEE2O0 compound Circuit system of logic provide Objective: Students volition be satisfactory to construct Logic Circuits using Integrated Circuits. In this exercise you will single-valued function integrated lick logic stops to digit networks of logic gates. The chips you will use be from the 74xxx serial publication of chips. These chips hump in a package cognise as elude (Dual In-line pegleg 1 bundle) because the plastic container has two parallel rows of pins to unite the informal rounds to a circuit board. Inside Fig. 1: decline Package the package ar networks of transistors designed to perform a wide of the mark variety of functions. from each one chip is labeled with a number which indicates what the function of the chip is. Pin 1 is sequester by a small circular indent or a U-shaped indent atone end of the chip; the keep pins be nu mbered counterclockwise around the chip. The 7400 chip, for example, contains four 2-input NAND gates, but chips are available with all types of logic gates, timers, counters, adders and subtractors, encoders and decoders, and memory, to name a few. In fact in the late sixties and early seventies, broad(a) computers were make by soldering thousands of these chips to expressher on circuit boards. They are still in use today in electronic devices where the power of a complete microprocessor is not needed. The 74xxx series of chips use bipolar transistors in a type of circuit known as Transistor-Transistor Logic (TTL). While MOS and CMOS technologies are more bunch and energy efficient than TTL, they are easily damage by static electricity. TTL circuits operate with 5 Volts DC power. Each chip must have the common or minus connected to the Ground (GND) pin, and +5 volts connected to the pin attach Vcc (Common aggregator Voltage). The numbers on the chips also provide differen t data about the contents of the package: T! he number is usually in the format MM74TTXX in which MM is the Manufacturers...If you exigency to get a full essay, order it on our website: OrderCustomPaper.com
