PURPOSE: A collision detection apparatus using parity in common data bus and a method thereof are provided to transmit data and parity simultaneously when transmitting data in a common data bus, receive these and then detect parity, thereby capable of detecting the existence of collision. CONSTITUTION: An MAC(Media Access Control) control unit(10) transmits/receives data and processes MAC frame data according to a collision signal detected from a data collision processing unit(20). The data collision processing unit(20) transmits/receives data between the MAC control unit(10) and a bus, produces the collision signal by using data and parity received from the bus and transmits the signal to the MAC control unit(10). A buffer unit(30) performs the buffering of data and parity when transmitting/receiving data between the data collision processing unit(20) and the bus.
