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.
