Abstract:
An apparatus having a 3. 3 volt power supply and a 5 volt power supply, wherein digital signals are processed on a 3. 3 volt basis which are translated to a 5 volt basis by a voltage translation circuit before being output. The voltage translator is comprised of an inverter for inverting an input signal. The inverter is powered by the 3. 3 volt power supply. A p-channel transistor having its source coupled to the 5 volt power supply and its gate driven by the output of the inverter is implemented. When the inverter generates a low logic, the p-channel transistor is turned on and outputs 5 volts. An n-channel transistor having its source coupled to ground and its gate driven by the output of the inverter is also implemented. When the output of the inverter is 3. 3 volts, the n-channel transistor is turned on, which pulls the output to ground.
