ABSTRACT:
An I/O buffer with minimized footprint; which is less susceptible to voltage spikes caused by switching noise, and which is adapted for used in a separate power bus arrangement. The buffer minimizes voltage spikes caused by switching noise by replacing the single large current surge that occurs during switching with smaller current surges at different times. This is accomplish by having two different drivers for the transitional and holding phases: a Transient Switching Circuit (TSC) and a Logic Holding Circuit (LHC). Generally, the TSC is operational to cause a change in the output signal when there is a change in the input signal. Conversely, the LHC is operational subsequent to the logic transition occurrence at the input signal to bring the output signal to the rail voltage.
