Note 1:
All specifications are 100% tested at T
A
= +25°C. Specification limits over temperature (T
A
= T
MIN
to T
MAX
) are guaranteed by
device characterization, not production tested.
Note 2:
The TSM934 comparator operates below 2.5V. Refer to the “Low-Voltage Operation: V+ = 1.5V (TSM984 Only)
”
section.
Note 3:
Low-to-high response time is due to a 1MΩ pullup resistor and a 100pF capacitive load, based after three time constants. A smaller
RC combination results in a faster response time.
