Abstract
A high voltage CMOS decoder and level translator for use in conjunction with EPROMS and EEPROMS utilizes additional series coupled field effect transistors maintained in an on condition so a to prevent the voltage across the pull-up and pull-down field effect transistors from exceeding their break down voltages. For example, in addition to a pull-up P-channel field effect transistor and a pull-down N-channel field effect transistor in the output inverter circuit, additional P-channel and N-channel field effect transistors are coupled in series between the pull-up and pull-down transistors to maintain the voltage across the pull-up and pull-down transistors from exceeding there breakdown voltages.
