The advantages of CMOS are as follows:

  • Low power consumption
  • It has a wider voltage variation 3v to 15vdc
  • The fan-out capacity of this device is high
  • high input resistance

CMOS stands for complimentary metal oxide semiconductor. Its specialties are its wide operating voltage (from 3 to 15 volts) and low power requirements. They are notoriously sensitive to static, which may ruin it.

CMOS may be substituted with HCMOS (hi speed CMOS) devices or even LS-TTL (low power transistor transistor logic) devices, provided the supply voltage, power dissipation and interfacing are kept in mind. A TTL with throw in the towel at above 5 volts. You may try 74HCXXX chips. Also consulting digital IC databooks will help.

A computer's motherboard is made up of many essential components including the complementary metal-oxide semiconductor (CMOS) battery. Without this battery, a computer cannot properly function or even boot at all. While a CMOS battery is designed to last up to 10 years, it is possible for it to weaken and suffer failure, which will become evident in the computer's performance.

The function of CMOS RAM is to store information your computer needs when it boots up, such as Disk Drive details, Keyboard type and Video Interface information, details of the configuration of the PCI Bus slots and even a Password to restrict access to the CMOS.

If the battery that powers your CMOS RAM dies, all this information is lost, and your PC will boot with the CMOS basic defaults. In most cases, this means you'll have no access to your Disk Drives until you supply the CMOS with the necessary information.

The information stored in CMOS is required by your computer's Basic Input/Output System, or BIOS.

One of the disadvantages of CMO's is it has high propagation delays. Another disadvantage of CMO's is that they have low noise margins.

why use cmos when troubleshooting?

You Can use cmos to change date and time, change the boot sequence, and use it to overclock the system.
