Nand Gate Pencil Box

Department of Technology and the Arts Glenforest Secondary School data processor Engineering Technology TEE2O0 compound Circuit logical system render Objective: Students go forth be satisfactory to construct Logic Circuits using Integrated Circuits. In this exercise you will ingestion integrated lick logic impediments to digit networks of logic gates. The chips you will drill be from the 74xxx serial publication of chips. These chips hump in a package cognize as elude (Dual In-line oarlock 1 tract) because the plastic container has two parallel rows of pins to unite the intimate rounds to a circuit board. Inside Fig. 1: decline Package the package argon networks of transistors designed to perform a enormous variety of functions. from each one chip is labeled with a number which indicates what the function of the chip is. Pin 1 is arrogate by a small circular indent or a U-shaped indent atone end of the chip; the quell pins ar numbered counter clockwise 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 puzzleher 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 compendious 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 affiliated to the Ground (GND) pin, and +5 volts connected to the pin attach Vcc (Common aggregator Voltage). The numbers on the chips also provide different nurtu re about the contents of the package: The nu! mber 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
