What is the most popular IC used in timing circuits? Correct Answer 555

555 timer is one of the most popular IC used in timing circuits.

It is an integrated circuit used in a variety of timer, pulse generation, and oscillator applications.

The Pin configuration of IC-555 is as shown:

  • Pin 5 of 555 Timer is the control pin. 
  • This makes the oscillator cycle more consistent.
  • This pin can also be used to change the internal voltage reference to allow modifying the oscillator frequency or duty cycle.

 

It has three operating modes:

Astable Mode: In this mode, the 555 IC can be used as an oscillator, pulse generator, logic clocks, etc.

Monostable mode: In this mode, the 555 functions as a ‘one-shot’ pulse generator and finds use in frequency divider, timers, pulse detection, touch switches.

Bistable mode: In this mode, the 555 IC can be operated as a flip-flop, latches.

Based on the paragraph given below answer the following question: The traditional methods of combinational circuits involve simplification and realization using gates. Using these methods, complex functions have been integrated and are easily available in IC form. There is an attractive array of devices like a multiplexer, demultiplexer, decoders, comparators, parity generators/checkers, which significantly reduce IC package count there by reducing the system cost. The system design is greatly simplified because the laborious and time-consuming simplification methods are generally not required with these devices. This also improves the reliability of the system by reducing the number of external wired connections. But they have some limitations as well. Different memories like ROM, PROM can also be used to implement combinational circuits without much simplification.   Consider the following digital circuits. 1. Multiplexers 2. Read Only Memories 3.
