How much voltage does the MC1489 can take?(a) 12V(b) 5V(c) 3.3V(d) 2.2

1.	How much voltage does the MC1489 can take?(a) 12V(b) 5V(c) 3.3V(d) 2.2VI got this question in my homework.This is a very interesting question from RS232 in division Basic Peripherals of Embedded Systems
Answer» The correct answer is (b) 5V Best explanation: The MC1489 is an interface chip which can take a5V and GENERATE internally the other VOLTAGES which are NEEDED to meet the interface specification.
