1.	What is the function of an enable input on a multiplexer chip?(a) To apply Vcc(b) To connect ground(c) To active the entire chip(d) To active one half of the chipThe question was asked in semester exam.This intriguing question comes from Multiplexers (Data Selectors) topic in portion Combinational Circuits of Digital Circuits
Answer» The correct CHOICE is (c) To ACTIVE the entire chip The best explanation: Enable input is used to active the chip, when enable is HIGH the chip works (ACTIVE), when enable is LOW the chip does not work (MEMORY). However, Enable can be Active-High or Active-Low, indicating it is active either when it is connected to VCC or GND respectively.
