A TTL chip can drive a CMOS chip without modification if the CMOS chip is designed to do so. Many large scale CMOS chips, such as microprocessors, have LS (or equivalent) TTL IO pins, so you can drive them directly. In the absence of that, you can use a pull up resistor, but you need to look carefully at fan-in, fan-out, rise time, fall time, and power requirements, in order to assure proper operation. It is best to use chips that are designed for the application, such as TTL to CMOS buffers.

Can a CMOS gate adequately drive a common LED?

You will have to check the datasheets for both the CMOS gate and the LED, then if the CMOS gate's rated output current is enough to light the LED you will need to do a little arithmetic using Ohm's law to calculate the resistor to put in series with the LED to limit current and avoid damaging the parts.


What are the applications of CMOS?

cmos technology is used in low power applications in vlsi and also used in image processing.cmos inverter has many applications like oscillator,amplifier and also used in analog transmission,digital applications etc.,


How digital IC of two different logic families can be connected on a single chip?

by using buffers however while the logic function for each family remains the same incompatibility is clearly evident. ANSWER: On a single chip it would be handled internally as an example TTL input CMOS output or vice verse


Which hardware component contains instructions that are used during the booting of the computer?

That would be firmware such as the ROM BIOS or the EFI. That is Read-Only Memory or a modern variation. BIOS stands for Basic Input/Output System, while the newer technology EFI stands for Extensible Firmware Interface.ROM doesn't require in any batteries. Even EPROM, EEPROM, and NVRAM don't use batteries. What did use batteries was the CMOS memory which may be separate from the ROM, though it could be in the same chip or part of the real-time clock chip. That was not Read-Only Memory, since you would use the CMOS setup to change it. If it can't be changed, no battery would be required. When that battery dies, you only use the hardware settings, not the code that brings up the computer.


How does a high out of a cmos gate operate a cmos load?

In a CMOS (Complementary Metal-Oxide-Semiconductor) circuit, a high output from a CMOS gate indicates that the output transistor (typically the PMOS transistor) is turned on, allowing current to flow from the supply voltage (V_DD) to the output node. This high output state effectively charges the load capacitance connected to the output, bringing the voltage at the output node close to V_DD. Conversely, the NMOS transistor is off, preventing any current flow to ground, thus maintaining the high state. The combination of these actions allows the CMOS gate to efficiently drive the load while consuming minimal power.
