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 30Ω. This is applicable with any
combination of outputs using continuous duty.
The propagation delay of the part is minimally affected by reflections
when terminated only by the TTL inputs of other devices.
Performance may be improved by full or partial line termination.
