Question

To ensure that a negative fluctuation does not trigger an unwanted downward transition by pulling the input down through VIT−, we must choose

(a) minimum hysteresis

(b) maximum hysteresis

(c) all of the mentioned

(d) none of the mentioned

The question was posed to me in my homework.

I need to ask this question from Digital Inputs, Outputs and Delays topic in portion MSP430 Microcontroller of Microcontroller

Answer 1

Correct choice is (a) minimum hysteresis

For explanation I would say: To ensure that a negative fluctuation does not trigger an unwanted downward transition by pulling the input down through VIT−, we must choose a minimum hysteresis of 0.3V.
