*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.
