The RasPi IO pins are 3.3V only. The RasPi can be damaged if IO pins are connected to out-of-range voltages, escpecially a voltage higher than Vcc+x. To connect 5V peripherals properly, level shifting is necessary. A number of level shifting methods is discussed here http://elinux.org/RPi_GPIO_Interface_Circuits
