These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability. 2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace length of zero. recommended operating conditions MIN MAX UNIT Reference voltage, Vref 4.5 5.5 V Input clamping current IIK VI ≥ Vref 25 mA Input clamping current, IIK VI ≤ GND –25 mA TL7726C 0 70 Operating free-air temperature range, TA TL7726I –40 85 °C TL7726Q –40 125 electrical characteristics over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP‡ MAX UNIT VIK + Positive clamp voltage II = 20 mA Vref Vref + 200 mV VIK – Negative clamp voltage II = 20 mA – 200 0 mV IZ Reference current Vref = 5 V 25 60 µA Vref – 50 mV ≤ VI ≤ Vref 10 II Input current GND ≤ VI ≤ 50 mV –10 µA 50 mV ≤ VI ≤ Vref – 50 mV –1 1 ‡ All typical values are at TA = 25°C. switching characteristics specified at TA = 25°C PARAMETER TEST CONDITIONS MIN MAX UNIT t Settling time VI(system) = ±13 V, RI = 600 Ω, tt < 1 µs, 30 µs ts Settling time I(system) , Measured at 10% to 90%, I , See Figure 1 t µ , 30 µs |
