Note 2: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating

the device beyond its rated operating conditions.

Note 4: Reflow temperature profiles are different for lead-free and non-lead-free packages.

Note 5: Human body model, 100 pF discharged through a 1.5 k

Ω resistor. Machine model, 200 pF discharged directly into each pin.

Note 7: Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).

Note 8: Local temperature accuracy does not include the effects of self-heating. The rise in temperature due to self-heating is the product of the internal power

dissipation of the LM73 and the thermal resistance.

Note 9: This specification is provided only to indicate how often temperature data is updated. The LM73 can be read at any time without regard to conversion state

(and will yield last conversion result).

and SMBCLK pins to a high impedance state.

temperature conversion time, valid temperature will be available in the Temperature Register.

Note 13: A write to an invalid pointer address is not allowed. If the master writes an invalid address to the Pointer Register, (1) the LM73 will not acknowledge the

address and (2) the Pointer Register will continue to contain the last value stored in it.
