Description

The 74F3040 is a high current Line Driver composed of two 4-input NAND gates. It has been designed to deal with the transmission line effects of PC boards which appear when fast edge rates are used.

The drive capability of the 74F3040 is 67mA source and 160mA sink with a V_CC as low as 4.5V. This guarantees incident wave switching with V_OH not less than 2.0V and V_OL not more than 0.8V while driving impedances as low as 30. This is applicable with any combination of outputs using continuous duty.

The propagation delay of the part is minimally affected by reflections of the 74F3040 when terminated only by the TTL inputs of other devices. Performance may be improved by full or partial line termination.
