Does the level shifter converts the voltage levels between RS-232 and transistor-transistor logic.
A. True
B. False
This question was addressed to me in an online interview.
I would like to ask this question from Arduino in division Prototyping Embedded Devices of IOT
Correct choice is A. True
The best I can explain: Level shifters are used in multi-design, different blocks work on different voltage levels. So when a signal passes from one voltage domain to another voltage this is needed particularly when a signal passes from low level to high level.
