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. All voltage values are with respect to the network ground terminal. 2. 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. 3. 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 Supply voltage, VCC 1 7 V Output voltage VO (see Note 4) Transistor off RESET voltage 15 V Output voltage, VO (see Note 4) Transistor off RESET voltage 0 V Low-level output current, IOL RESET 24 mA High-level output current, IOH RESET –8 mA Operating free-air temperature, TA TL7759C 0 70 °C NOTE 4: RESET output must not be pulled down below GND potential. electrical characteristics over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS TL7759C UNIT PARAMETER TEST CONDITIONS MIN TYP‡ MAX UNIT VOL Low-level output voltage RESET VCC =4 3V IOL = 24 mA 0.4 0.8 V VOH High-level output voltage RESET VCC = 4.3 V IOH = –8 mA VCC–1 V VIT Input threshold voltage TA = 25°C 4.43 4.55 4.67 V VIT– g (negative-going VCC) TA = 0°C to 70°C 4.4 4.7 V V § Power up reset voltage RL =22kΩ TA = 25°C 0.8 1 V Vres§ Power-up reset voltage RL = 2.2 kΩ TA = 0°C to 70°C 1.2 V V ¶ Hysteresis at VCC input TA = 25°C 40 50 60 mV Vhys¶ Hysteresis at VCC input TA = 0°C to 70°C 30 70 mV IOH High-level output current RESET VCC = 7 V See Figure 1 VOH = 15 V 1 µA IOL Low-level output current RESET VCC = 7 V, See Figure 1 VOL = 0 V –1 µA ICC Supply current No load VCC = 4.3 V 1400 2000 µA ICC Supply current No load VCC = 5.5 V 40 µA ‡ Typical values are at TA = 25°C. § This is the lowest voltage at which RESET becomes active, VCC slew rate ≤ 5 V/µs. ¶ This is the difference between positive-going input threshold voltage, VIT+, and negative-going input threshold voltage, VIT–. |
