NOTES: 1. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which
the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see Electrical
Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when
the device is not operated under the listed test conditions.
2. The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX (maximum junction temperature), θ_JA
(junction to ambient thermal resistance), and T_A (ambient temperature). The maximum allowable power dissipation at any temperature is
PD_MAX = (TJMAX – T_A) /θ_JA or the number given in Absolute Maximum Ratings, whichever is lower. For the TCN4040, TJMAX = 125°C, and
the typical thermal resistance (θ_JA), when board mounted, is 185°C/W for the M package, 326°C/W for the SOT-23B-3 package, and 180°
C/W with 0.4” lead length and 170°C/W with 0.125” lead length for the TO-92-3 package.
3. The human body model is a 100pF capacitor discharged through a 1.5kΩ resistor into each pin. The machine model is a 200pF capacitor
discharged directly into each pin.
ELECTRICAL CHARACTERISTICS: Boldface type specifications apply for T_A = T_J = T_MIN to T_MAX. All other specifica-
tions; T_A = T_J = 25°C.
