Note 4: Human body model, 100 pF discharged through a 1.5 kΩ resistor. Machine model, 200 pF discharged directly into each pin. Charged device model (CDM)
simulates a pin slowly acquiring charge (such as from a device sliding down the feeder in an automated assembler) then rapidly being discharged.
Note 5: Reflow temperature profiles are different for lead-free and non lead-free packages.
Note 6: The maximum power dissipation must be de-rated at elevated temperatures and is dictated by T
allowable power dissipation at any temperature is P
air flow is listed in the following table.
Note 7: See the URL "http://www.national.com/packaging/" for other recommendations and methods of soldering surface mount devices.
Note 8: At the time of first pubication of this specification (Jan 2006), this specification applies to either Pentium or Xeon Processors on 90nm or 65nm process
when TruTherm is selected. When TruTherm is deselected this specification applies to an MMBT3904. This specification does include the error caused by the
variability of the diode ideality and series resistance parameters.
Note 9: Typical parameters are at T
Note 10: Limits are guaranteed to National's AOQL (Average Outgoing Quality Level).
Note 11: TUE (Total Unadjusted Error) includes Offset, Gain and Linearity errors of the ADC.
Note 12: Total Monitoring Cycle Time includes all temperature and voltage conversions.
Note 13: Leakage current approximately doubles every 20 °C.
Note 14: A total digital I/O current of 40 mA can cause 6 mV of offset in Vref.
Note 15: Timing specifications are tested at the TTL logic levels, V
to 1.4V.
