This specification applies over the full operating temperature range.

The enable time can slow considerably for some parts when temperature is <
20
°
C.
[3]
Delays that can occur after ENABLE and/or idle times have passed.
[4]
Guaranteed by design, not production tested.

I
trt(pu)
varies with temperature and V
CC
voltage, as shown in
Section 11.1 “Typical performance characteristics”
.
The connection circuitry always regulates its output to a higher voltage than its input. The magnitude of this offset voltage as a function
of the pull-up resistor and V
CC
voltage is shown in
Section 11.1 “Typical performance characteristics”
.
