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 may be exceeded provided that the input and output current ratings are observed. 2. The package thermal impedance is calculated in accordance with JESD 51. recommended operating conditions MIN MAX UNIT VCC Supply voltage 4.5 5.5 V VIH High-level input voltage 2 V VIL Low-level input voltage 0.8 V IOH High-level output current Q outputs, flags –8 mA IOL Low level output current Q outputs 16 mA IOL Low-level output current Flags 8 mA TA Operating free-air temperature –40 85 °C electrical characteristics over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP‡ MAX UNIT VOH VCC = 4.5 V, IOH = – 8 mA 2.4 V VOL Flags VCC = 4.5 V, IOL = 8 mA 0.5 V VOL Q outputs VCC = 4.5 V, IOL = 16 mA 0.5 V II VCC = 5.5 V, VI = VCC or 0 ±5 µA IOZ VCC = 5.5 V, VO = VCC or 0 ±5 µA ICC VI = VCC – 0.2 V or 0 400 µA ∆ICC§ VCC = 5.5 V, One input at 3.4 V, Other inputs at VCC or GND 1 mA Ci VI = 0, f = 1 MHz 4 pF Co VO = 0, f = 1 MHz 8 pF ‡ All typical values are at VCC = 5 V, TA = 25°C. § This is the supply current when each input is at one of the specified TTL voltage levels rather than 0 V or VCC. |
