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. The input and output voltage ratings can be exceeded if the input and output clamp current ratings are observed. 2. This value is limited to 4.6 V maximum. 3. The package thermal impedance is calculated in accordance with JESD 51. recommended operating conditions ’ALVC7805-20 ’ALVC7805-25 ’ALVC7805-40 UNIT MIN MAX MIN MAX MIN MAX UNIT VCC Supply voltage 3 3.6 3 3.6 3 3.6 V VIH High-level input voltage 2 2 2 V VIL Low-level input voltage 0.8 0.8 0.8 V IOH High level output current Q outputs flags VCC =3 V 8 8 8 mA IOH High-level output current, Q outputs, flags VCC = 3V –8 –8 –8 mA IOL Low level output current Q outputs flags VCC =3V 16 16 16 mA IOL Low-level output current, Q outputs, flags VCC = 3 V 16 16 16 mA TA Operating free-air temperature 0 70 0 70 0 70 °C electrical characteristics over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP‡ MAX UNIT VIK VCC = 3 V, IIK = –18 mA –1.2 V VOH Flags Q outputs VCC = 3 V to 3.6 V, IOH = –100 µA VCC–0.2 V VOH Flags, Q outputs VCC = 3 V, IOH = –8 mA 2.4 V Flags, Q outputs VCC = 3 V to 3.6 V, IOL = 100 µA 0.2 VOL Flags VCC = 3 V, IOL = 8 mA 0.4 V Q outputs VCC = 3 V, IOL = 16 mA 0.55 II VCC = 3.6 V, VI = VCC or GND ±5 µA IOZ VCC = 3.6 V, VO = VCC or GND ±10 µA ICC VI = VCC or 0 40 µA ∆ICC§ VCC = 3.6 V, Other inputs at VCC or GND, One input at VCC – 0.6 V 500 µA Ci VCC = 3.3 V, VI = VCC or GND 2.5 pF Co VCC = 3.3 V, VO = VCC or GND 5.5 pF ‡ All typical values are at VCC = 3.3 V, TA = 25°C. § This is the supply current for each input that is at one of the specified TTL voltage levels rather than 0 V or VCC. |
