In high-performance memory systems these decoders can be used to minimize the effects of system decoding. When used with high-speed memories, the delay times of these decoders are usually less than the typical access time of the memory. This means that the effective system delay introduced by the decoder is negligible. The DM74LS138 decodes one-of-eight lines, based upon the conditions at the three binary select inputs and the three enable inputs. Two active-low and one active-high enable inputs reduce the need for external gates or inverters when expanding. A 24-line decoder can be implemented with no external inverters, and a 32-line decoder requires only one inverter.

Advantages of multilevel inverters over pwm inverters?
harmonics reduced due to multi switching and output is approximately sine wave so filter design and cost reduced.DC link voltage is also reduced because of splitted source.
Is a router an input or output device?
That's sort of a trick question, as a router or hub are both input & output devices.
What are the 10 most significant components of a computer system?
Really there are only a few specific ones: Motherboard that takes the hardware CPU for the core processing Memory for relaying info Hard drive to store the info Video chip or card to display the video output optional: Sound chip/card for sound output
Data and instructions are stored on special ROM chips on the board and are called?
You might be talking about the BIOS, the Basic Input Output System stored on a ROM chip on the Computer Mainboard. It is the initial boot code run by the pc.
Is Plotter an input device or an output device?
Output
What main feature should you look for in DC to AC inverters?
Output in watts.
How to connect 74ls138 with 7 segment?
We cannot connect the 74ls138 straight with a seven segment display; for that we need a 7447(7 segment driver).
What is the HANA chip on an xbox 360?
it is the video output chip
Is 500 watts of AC power is being drawn on an inverter how many amps are being drawn on the batteries powering the inverter?
Inverter efficiencies vary about 50% when a small about of power is being used, to over 90% when the output is approaching the inverters rated output. Your question cannot be answered without knowing the inverters rated output.
What is plural possessive form of inverters?
The possessive form of the plural noun inverters is inverters'.
Is a chip and PIN an input or output device?
Input! x
The unit that transforms input into output is known as?
Bios chip
What is Decoder IC 74LS138?
It's an IC where the input is a 3 bit binary number. The output has 8 pins, one for each of the possible input values. For example, if the input is 000, the output pin called Y0 will the activated because that cooresponds to zero while all other pins will stay the same.
What are types of inverters?
Basically there are three types of inverters 1) Square wave Inverters 2) Quasi Square wave or Modified Square wave Inverters 3) True/Pure Sine wave Inverters The emerging trend among Inverters could be titled to Multi-Level Inverters which aim at the Increasing of Inverter Efficiency along with reduced Inverter Cost
What is cmos buffer?
A CMOS buffer is two stage inverter, or two inverters connected together in such a way that the output of first goes directly into second one.
The basic input and output system is stored on what type of chip?
ROM
What is rotary inverter?
"Rotary Inverter: In a rotary inverter, DC electricity input powers a DC motor that turns an AC generator. Rotary inverters are reliable and produce a pure sine-wave output. These inverters have automatic load demand: they begin operation once a load is activated, and shut down when the load is removed. Disadvantages of a rotary inverter are lack of frequency control, low surge capability (50% above maximum rating) and lower efficiency (50% to 80%). Rotary inverters are not as common as electronic inverters."
