Tri-state
■
Pad 8 open circuit or >0.6Vs output enabled
■
< 0.2Vs Tri-state
■
When Tri-stated, the output stage is disabled for all
output options, but the oscillator and compensation
circuit are still active
(current consumption <1mA)
Storage Temperature Range
■
–55 to 125°C
Environmental Specification
■
