Logic Gates Review

Logic Gates OR gate – 1 if either input is 1 – 0 if they both are 0

Logic Gates AND gates – 1 if both inputs are 1 – 0 if either is 0

CMOS Logic – Gates always paired

CMOS Gates NOT OR

Boolean Operators Truth Table : – Shows every combination of inputs and their output: In1In2Out

Logic Gates Digital electronics : design of binary systems Gates are basic building block: at tip means NOT

Basic Rules – 1 input NOT – Output is 1 if input is 0 – Output is 0 if input is 1 If it is not raining my drive is easier InOut 01 10

Basic Rules – 2 inputs AND – 1 if both inputs 1 – 0 otherwise OR – 1 if either input is 1 – 0 if both are 0 XOR (exclusive OR) – 1 if only one input is 1 – 0 if both inputs are 0 or 1 In1In2Out In1In2Out In1In2Out
