Doug Schroeder Method, Double ic

theory/hypothesis is merely an observation of an event or occurrence that covers only that observation.

even then the theory/hypothesis of the observation may only be partially correct and even occasionally, not correct at all.

when there is a variation of the original observation then the current theory/hypothesis may not work, or be relevant, at all.

it would appear that the posted observation is suggesting that the ics being used are inadequate and could be better... just an observation

@rcprince a single cable assembly having 2 IC’s in parallel with single termination connectors at both ends of the assembly provides one solution to your concern of using 2 Y-signal splitters with 2 IC’s (i.e., avoiding adding more connectors to the signal path).

See this post by way of example:
