* Specifications for an ML145407 powering an ML145406 with three additional drivers/receivers.

** Specification is for one Tx output pin to be shorted at a time. Should all three driver outputs be shorted simultaneously, device power dissipation

limits could be exceeded.

*** This condition could exceed package limitations.
