If you dig into the Kicad schematic, the manufacturer part number for the level translators is actually SN74CBTD3861DW, which is designed for 5V operation: http://www.ti.com/product/SN74CBTD3861 The 74CBTLV3861 is left-over from using one of the default parts in the KiCAD libraries which has the same schematic symbol and pinout, I just forgot to change the value. -- Charles Steinkuehler [email protected] -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
