DESCRIPTION
Updated the F5 MicroCan face brand with the latest per PCN H020201.
Change the last sentence of the Parasite Power section to “The
advantages of parasite power are two-fold: 1) by parasiting off this
input, battery power is not consumed for 1-Wire ROM function
commands, and 2) if the battery is exhausted for any reason, the ROM
may still be read normally. The remaining circuitry of the DS1992 and
DS1993 is solely operated by battery energy.”
In the DC Electrical Characteristics section, relocated V PUP from the
header to the EC table, changed V ILMAX from 0.8V to 0.3V, and
removed the V OH parameter for the 1-Wire pin.
Updated the part numbers in the Ordering Information table to indicate
a lead(Pb)-free/RoHS compliant product.
Updated the UL certificate reference in the Common iButton Features
and Physical Specifications sections; added the Package Information
