* 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.
