It is quite common to make use of logic gates from one among two families of digital ICs: TTL and CMOS. The TTL family is often recognized because the 74xx household, after the naming of many of TTL ICs fabricated by Texas Devices. Logic capabilities in this family are mainly implemented utilizing the TTL technology. This household consists of many simple and complex logic capabilities, such because the 7400 that features 4 NAND gates, in addition to different logic features. Among others, we will discover NOR gates, AND gates, inverters, buffers, decoders, frequency dividers, counters, latches, flip-flops, adders, memories, and registers.
But Westinghouse, armed with the Tesla patents, might show that AC was a way more efficient different. The climactic battle in the Conflict of the Currents befell on the colossal Chicago Columbian Exposition of 1893-94. Westinghouse was able to provide power for 10M16DAF484I6G much less than what Edison would have charged. He won the contract and wired the fair based on the Tesla system. Because the exposition opened, 1000’s of bright lamps flashed on, startling truthful-goers. The demonstration dispelled public fears of alternating present, and AC grew to become the usual for power methods.
