Output Short–Circuit Current 5.5 V Tx1 – Tx3 shorted to * Specifications for an MC145407 powering an MC145406 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. ...

... MC145406 or MC145403. If there is no requirement to support a second interface device and/or the charge pump is not being used to power any other com- ponents, the MC145407 is capable of complying with EIA–232–E and V.28 with smaller value charge pump caps. Table 1 summarizes driver performance with both 2.2 F and 1 ...
