It has been designed to dealwith the transmission line effects of PC boards which appear whenfast edge rates are used.TYPICALTYPICALTYPEPROPAGATIONSUPPLY CURRENTThe 74F3038 can sink 160mA with a VCC as low as 4.5V. ThisDELAY(TOTAL)guarantees incident wave switching with VOL not more than 0.8Vwhile driving impedances as low as 30Ω. This is applicable with any74F30386.0ns17mAcombination of outputs using continuous duty.The AC specifications for the 74F3038 were determined using theORDERING INFORMATIONstandard FAST load for open-collector parts of 50pF capacitance, aCOMMERCIAL RANGEPACKAGE500Ω pull-up resistor and a 500Ω pull-down resistor.
