When transistors are used in digital circuits they usually operate in
- A. active region
- B. breakdown region
- C. linear region
- D. saturation and cutoff regions
Step-by-step solution
In digital circuits, transistors function as switches, operating in either cutoff (off) or saturation (on) regions for bipolar junction transistors (BJTs), or cutoff and triode/linear regions for MOSFETs. The option 'saturation and cutoff regions' corresponds to the typical switching behavior in digital logic, avoiding active/linear regions used for analog amplification and breakdown regions which are damaging.
