Is it prohibited to bundle pins described "via individual resistors"?

Latest Updated:08/01/2005


When handling unused pins, is it prohibited to bundle pins described as "via individual resistors" and pull them all up or down with a single resistor?


Yes, this is prohibited.
Pins that are thus described are I/O pins that include outputs that are not open collector or open drain.
Output conflicts may occur for this reason, so wired OR connection is not possible.
