Question

Is it possible to interface an IC with a different technology such as TTL to HCS12 ports? What are the conditions in terms of electrical parameters that need to be satisfied for this purpose?

Answer 1

The condition is true when their voltage and current specifications with their impedance are matched or complementary to each other.

Step-by-step explanation:

Solution

Yes it is possible or true to interface an IC with a different technology like the TTL to HCS12 ports. but the condition is that their current and voltage specifications should be matched and their impedance and power also should be matched.

What this implies is that both their voltage and current requirements should be complementary to each other so as their impedance.
