Abstract
Robust high-voltage tolerant I/O that does not need process options is presented, demonstrated on 5.5 V tolerant open-drain I/O in a 2.5 V 0.25 μm CMOS technology. Circuit techniques limit oxide stress and hot-carrier degradation, resulting in hundreds of years extrapolated lifetime for 5.5 V pad voltage swing, 2.2 V supply voltage, 10 MHz switching frequency. The shown concepts are also implemented in other types of I/O and can easily be scaled towards newer processes
