DS1780
Note: To properly implement the NAND TREE test on the PCB, no pins listed in the tree should be
connected directly to power or ground; if a pin is needed to configure as a permanent low such as an
address, it should be connected to ground through a low value resister such as 330 (to allow the ATE
(Automatic Test Equipment) to drive it high.
