Umm, Ok,
Maybe I'm missing something but, negative, is negative. It is a function of the voltage divider on the output. This chip can be set to fixed or variable. This clearly was not my question. If you look at the logic states expressed in the datasheets aforementioned, you will see that ON-Semi specs that a HIGH specifies an "OFF" as TI specs a HIGH as output "ON". The schematics are effectively identical.
Thanks for your input,
Chris
