Unused inputs should be tied to VCC through a pullup resistor of approximately 5 kW or greater to prevent them from floating. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004. 4. All VCC and GND pins must be connected to the proper-voltage power supply. electrical characteristics over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS VCC TA = 25°C MIN MAX UNIT PARAMETER TEST CONDITIONS VCC MIN TYP MAX MIN MAX UNIT IOH = 50 mA 4.5 V 4.4 4.4 IOH = –50 mA 5.5 V 5.4 5.4 VOH IOH = 16 mA 4.5 V 3.94 3.7 V OH IOH = –16 mA 5.5 V 4.94 4.7 IOH = –24 mA† 5.5 V 3.85 IOL =50 mA 4.5 V 0.1 0.1 IOL = 50 mA 5.5 V 0.1 0.1 VOL IOL =16mA 4.5 V 0.36 0.5 V OL IOL = 16 mA 5.5 V 0.36 0.5 IOL = 24 mA{ 5.5 V 0.5 II VI = VCC or GND 5.5 V ±0.1 ±1 mA IOZ VO = VCC or GND 5.5 V ±0.5 ±10 mA ICC VI = VCC or GND, IO = 0 5.5 V 8 160 mA DICC‡ One input at 3.4 V, Other inputs at GND or VCC 5.5 V 0.9 1 mA Ci VI = VCC or GND 5 V 4.5 pF Co VI = VCC or GND 5 V 12 pF † Not more than one output should be tested at a time, and the duration of the test should not exceed 10 ms. ‡ This is the increase in supply current for each input that is at one of the specified TTL-voltage levels rather than 0 V to VCC. timing requirements over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted) (see Figure 1) TA = 25°C MIN MAX UNIT MIN MAX MIN MAX UNIT tw Pulse duration, LE high 4 4 ns tsu Setup time, data before LE ↓ 1 1 ns th Hold time, data after LE ↓ 5 5 ns |
