However, the Eniac could hurt you a lot more than a chip could if it fell on you—it was feet long, 10 feet high, 3 feet deep, and consumed puertas logicas ttl y cmos, watts of power!
Ten years before the bipolar junction transistor was invented, the principles of operation were patented for another type of transistor, called the metal-oxide semiconductor field effect transistor MOSFETor simply MOS transistor. Even then, MOS circuits lagged bipolar circuits considerably in speed, and were attractive only in selected applications because of their lower power consumption and higher levels of integration.
By far the majority of new large-scale integrated circuits, such as microprocessors and memories, use CMOS. Likewise, small- to medium-scale applications, for which TTL was once the logic family of choice, are now likely to use CMOS devices with equivalent functionality but higher speed and lower power consumption.
CMOS puertas logicas ttl y cmos is both the most capable and the easiest to understand commercial digital logic technology.
As suggested puertas logicas ttl y cmos Figurean input voltage applied to one terminal controls the resistance between the remaining two terminals.
The terminals are called gate, source, and drain. However, real logic circuits process electrical signals such as voltage levels. In any logic circuit, there is a range of voltages or other circuit conditions that is interpreted as a logic 0, and another, nonoverlapping range that is interpreted as a logic 1.
Subfamilias CMOS, by alda perez on Prezi
A typical CMOS logic circuit operates from a 5-volt power supply. Such a circuit may interpret any voltage in the range 0—1. Voltages in the intermediate range are not expected to occur except during signal transitions, and yield undefined logic values i.
CMOS circuits using other power supply voltages, such as puertas logicas ttl y cmos. The simplest CMOS circuit, a logic inverter, requires only one of each type of transistor, connected as shown in Figure a. The power supply voltage, VDD, typically may be in the range 2—6 V, and is puertas logicas ttl y cmos often set at 5.
Ideally, the functional behavior of the CMOS inverter circuit can be characterized by just two cases tabulated in Figure b: Thus, Q1 presents a small resistance between the output terminal and ground, and the output voltage is 0 V. With the foregoing functional behavior, the circuit clearly behaves as a logical inverter, since a 0-volt input produces a 5-volt output, and vice versa nd the output voltage is 5.

A k-input gate uses k p-channel and k n-channel transistors. CMOS gates with more than two inputs can be obtained by extending series-parallel designs on Figures and in the obvious manner.
This refers to the number and type of inputs that are connected to a given output. If too many inputs are connected to an output, the DC noise margins of the circuit may be inadequate. Fanout may also affect the speed at which the output changes from one state to another. Puertas logicas ttl y cmos las principales fuentes de ruido se destacan: Figure a shows a NAND gate with its inputs tied together.
You can also tie unused inputs to a constant logic value. It is also possible to tie unused inputs directly to the appropriate power-supply rail. Esto es usado en algunas aplicaciones tales como:
