Effect of Temperature on Timeout
Period (t
RPU
)
The timeout period (t
) determines how long the
device remains in the reset condition. This is controlled
by an internal RC timer and is effected by both V
and
temperature. The graph shown in Figure 2-3 shows
typical response for different V
DD
values and tempera-
tures.
