Test conditions according to “A.C. Test Conditions” table. 7. Tested initially and after a design or process change that affects this parameter. 8. tPU is the delay between the time VCC is stable and the device is ready to accept commands. Table 6. THERMAL CHARACTERISTICS (Air velocity = 0 m/s, 4 layers PCB) (Notes 9 and 10) Part Number Package qJA qJC Units CAT34C02Y TSSOP 64 37 °C/W CAT34C02VP2 TDFN 92 15 °C/W CAT34C02HU3 UDFN 101 18 °C/W CAT34C02HU4 UDFN 101 18 °C/W 9. TJ = TA + PD * qJA, where: TJ is the Junction Temperature, TA the Ambient Temperature, PD the Power dissipation. Example: CAT34C02VP2, VCC = 3.0 V, ICCmax = 1 mA, TA = 85°C: TJ = 85°C + 3 mW * 92°C/W = 85.276°C. 10.TJ = TC + PD * qJC, where: TC is the Case Temperature, etc. Table 7. A.C. TEST CONDITIONS Input Levels 0.2 VCC to 0.8 VCC Input Rise and Fall Times ≤ 50 ns Input Reference Levels 0.3 VCC, 0.7 VCC Output Reference Levels 0.5 VCC Output Load Current Source: IOL = 3 mA (VCC ≥ 2.5 V); IOL = 1 mA (VCC < 2.5 V); CL = 100 pF |
