What is the 555 IC timer measured in?

The 555 IC timer is typically measured in units of time, such as microseconds (µs), milliseconds (ms), or seconds (s). It can be used to generate precise timing intervals for various applications.


What is the function of a 555 IC?

The 555 IC is a universal timer circuit. Via the addition of external components (resistors, capacitors) the designer can generate various timing waveforms.


Why 555 timer named as 555?

A 555 timer basically consists of: # A voltage divider circuit, # Two comparators, # An SR flip-flop, and # Two (bipolar) transistors: one NPN (discharge) and one PNP (reset), as can be seen in its block diagram. The voltage divider consists of three 5Kohm resistors, so that we get (1/3)Vcc and (2/3)Vcc; we use these voltages as references for the comparators. The three 5K resistors, along with IC's main applications being in timer and multi-vibrator circuits, give it the name 555 timer.
