VIN<0.2V VIN>VCC−0.2V — 5 500 µA ∆I CC Quiescent Power Supply Current TTL inputs HIGH VCC= Max., VIN = 3.4V [14] — 0.5 1.5 mA ICCD Dynamic Power Supply Current[15] VCC=Max., Outputs Open OEAB=OEBA=VCC or GND One Input Toggling, 50% Duty Cycle VIN=VCC or VIN=GND — 75 120 µA/ MHz IC Total Power Supply Current[16] VCC=Max., Outputs Open f0 =10MHz (CLKAB) 50% Duty Cycle OEAB=OEBA=VCC LEAB = GND, One Bit Toggling f1 = 5MHz, 50% Duty Cycle VIN=VCC or VIN=GND — 0.8 1.7 mA VIN=3.4V or VIN=GND — 1.3 3.2 VCC=Max., Outputs Open f0 = 10MHz (CLKAB) 50% Duty Cycle OEAB=OEBA=VCC LEAB=GND Eighteen Bits Toggling f1=2.5MHz, 50% Duty Cycle VIN=VCC or VIN=GND — 3.8 6.5[17] VIN=3.4V or VIN=GND — 8.5 20.8[17] Notes: 13. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type. 14. Per TTL driven input (VIN=3.4V); all other inputs at VCC or GND. 15. This parameter is not directly testable, but is derived for use in Total Power Supply. 16. IC=IQUIESCENT + IINPUTS + IDYNAMIC IC =ICC+∆ICCDHNT+ICCD(f0/2 + f1N1) ICC = Quiescent Current with CMOS input levels ∆I CC = Power Supply Current for a TTL HIGH input (VIN=3.4V) DH = Duty Cycle for TTL inputs HIGH NT = Number of TTL inputs at DH ICCD = Dynamic Current caused by an input transition pair (HLH or LHL) f0 = Clock frequency for registered devices, otherwise zero f1 = Input signal frequency N1 = Number of inputs changing at f1 All currents are in milliamps and all frequencies are in megahertz. 17. Values for these conditions are examples of the ICC formula. These limits are specified but not tested. |
