Board features two 8-bit non-inverting bus transceiver LVXC3245. All inputs and outputs are 5V tolerant. LVCC3245 is manufactured in advanced dual metal CMOS technology. This bus transceiver contains two separate supply rails that allow transition from a 5V to 3.3V system environment. Board contains MC33269DT-3.3 - 3.3V Voltage regulator which can be enabled using J17 jumper and create 3.3v power supply for Low Voltage Port.
