Added bullet “Water resistant or waterproof if placed inside DS9107 iButton capsule (Exceeds Water
Resistant 3 ATM requirements)”
Deleted “application pending” from UL bullet and safety statement
Added text to Detailed Description section: Note that the initial sealing level of DS1921G achieves
IP56. Aging and use conditions can degrade the integrity of the seal over time, so for applications
with significant exposure to liquids, sprays, or other similar environments, it is recommended to
place the Thermochron in the DS9107 iButton capsule. The DS9107 provides a watertight enclosure
that has been rated to IP68 (See www.maxim-ic.com/AN4126)
