Hi
 I would suspect that it was not intended to be tied
directly to a bus. One would normally have some robust
receiver that would invert the signal. In the days when
it was designed, the 0 to 2.5V TTL bus was just starting
out. Many had other voltage ranges and required some
conditioning. The simplest conditioning circuits usually
had an inverted signal out.
