6. Test conditions according to “A.C. Test Conditions” table.
7. Tested initially and after a design or process change that affects this parameter.
8. t_PU is the delay between the time V_CC is stable and the device is ready to accept commands.

9. T_J = T_A + P_D * q_JA, where: T_J is the Junction Temperature, T_A the Ambient Temperature, P_D the Power dissipation.
Example: CAT34C02VP2, V_CC = 3.0 V, I_CCmax = 1 mA, T_A = 85°C: T_J = 85°C + 3 mW * 92°C/W = 85.276°C.
10. T_J = T_C + P_D * q_JC, where: T_C is the Case Temperature, etc.
