Note 1:
All specifications are 100% tested at T
A
= +25°C. Specification limits over temperature (T
A
= T
MIN
to T

) are guaranteed by
device characterization, not production tested.
Note 2:
The TSM924 comparator operates below 2.5V. Refer to the “Low-Voltage Operation: V+ = 1.5V (TSM924 Only)
”
section.
