Abstract
An output buffer with feedback to a predriver circuit such that the effective size of the predriver buffers are momentarily adjusted to favor a particular transition (i.e., low-to-high or high-to-low). The delayed output selectively alters the input threshold characteristic of the predriver circuit to favor the appropriate transition. Thus, the time during which the output drivers are subject to a crowbar current is reduced over previous devices.
