Stray capacitance can be introduced when connecting the LMT01-SP through a long wire. This stray capacitance

influences the signal rise and fall times. The wire inductance has negligible effect on the AC signal integrity. A

simple RC time constant model as shown in Figure 23 can be used to determine the rise and fall times.

Take care to ensure that the LMT01-SP voltage drop does not exceed 300 mV under reverse bias conditions, as

given in the Absolute Maximum Ratings.

7.4 Device Functional Modes

The only functional mode the LMT01-SP has is that it provides a pulse count output that is directly proportional to

temperature.
