Abstract
A method of generating multiple gating signals for a multi-gated input/output (I/O) system. The system includes an output level shifter and an output driver which are coupled in series between an output node of a core circuit and an external terminal of a corresponding system. The method includes: generating first and second gating signals having corresponding first and second waveforms, the first waveform transitioning from a non-enabling state to an enabling state before the second waveform transitions from the non-enabling state to the enabling state; receiving the first gating signal at the output level shifter; and receiving the second gating signal at the output driver.
