Electrical parameters
Static latch-up
● LU: 2 complementary static tests are required on 10 parts to assess the latch-up
performance. A supply overvoltage (applied to each power supply pin) and a current
injection (applied to each input, output and configurable I/O pin) are performed on each
sample. This test conforms to the EIA/JESD 78 IC latch-up standard. For more details,
refer to the application note AN1181.

Thermal characteristics
The maximum chip junction temperature (T_Jmax) must never exceed the values given in
Table 16: General operating conditions on page 40.
The maximum chip-junction temperature, T_Jmax, in degrees Celsius, may be calculated
using the following equation:
T_Jmax = T_Amax + (P_Dmax x Θ_JA)
Where:
● T_Amax is the maximum ambient temperature in ° C
● Θ_JA is the package junction-to-ambient thermal resistance in ° C/W
● P_Dmax is the sum of P_INTmax and P_I/Omax (P_Dmax = P_INTmax + P_I/Omax)
● P_INTmax is the product of I_DD and V_DD, expressed in Watts. This is the maximum chip
internal power.
● P_I/Omax represents the maximum power dissipation on output pins
Where:
P_I/Omax = Σ (V_OL*I_OL) + Σ((V_DD-V_OH)*I_OH),
taking into account the actual V_OL/I_{OL and} V_OH/I_OH of the I/Os at low and high level in
the application.
