* Specifications for a MC14570X powering a MC145406 or MC145403 with three additional drivers/receivers.
** Specification is for one Tx output 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.
