Note 2: The TSM934 comparator operates below 2.5V. Refer to the “Low-Voltage Operation: V+ = 1.5V (TSM984 Only)

Note 3: Low-to-high response time is due to a 1M

Ω pullup resistor and a 100pF capacitive load, based after three time constants. A smaller

RC combination results in a faster response time.
