All timing specifications are for the worst-case response. This includes
output contact operate times and standard BESTlogicPlus operation
timing but excludes input debounce timing and nonstandard logic
configurations. If a nonstandard logic scheme involves feedback, then
one or more BESTlogicPlus update rate delays must be included to
calculate the worst-case delay. An example of feedback is logic
outputs driving logic inputs. For more information, see BESTlogicPlus.
