It’s quite common to make use of logic gates from one among two households of digital ICs: TTL and CMOS. The TTL family is often known because the 74xx household, after the naming of a lot of TTL ICs fabricated by Texas Devices. Logic features in this household are mainly carried out using the TTL know-how. This family consists of many easy and complex logic functions, such as the 7400 that includes four NAND gates, in addition to other logic features. Among others, we can discover NOR gates, AND gates, inverters, buffers, decoders, frequency dividers, counters, XC6SLX45-2CSG324I latches, flip-flops, adders, memories, and registers.

However Westinghouse, armed with the Tesla patents, might present that AC was a far more environment friendly alternative. The climactic battle in the Battle of the Currents passed off at the colossal Chicago Columbian Exposition of 1893-94. Westinghouse was in a position to produce power for a lot less than what Edison would have charged. He gained the contract and wired the honest primarily based on the Tesla system. Because the exposition opened, hundreds of bright lamps flashed on, startling truthful-goers. The demonstration dispelled public fears of alternating current, and AC grew to become the usual for power methods.
