Unit ICC Quiescent Power Supply Current VCC=Max. VIN<0.2V VIN>VCC-0.2V — 5 500 µA ∆I CC Quiescent Power Supply Current (TTL inputs HIGH) VCC=Max., VIN=3.4V [9] — 0.5 1.5 mA ICCD Dynamic Power Supply Current[10] VCC=Max., One Input Toggling, 50% Duty Cycle, Outputs Open, OE=GND VIN=VCC or VIN=GND — 60 100 µA/MHz IC Total Power Supply Current[11] VCC=Max., f1=10 MHz, 50% Duty Cycle, Outputs Open, One Bit Toggling, OE=GND LE = VCC VIN=VCC or VIN=GND — 0.6 1.5 mA VIN=3.4V or VIN=GND — 0.9 2.3 VCC=Max., f1=2.5 MHz, 50% Duty Cycle, Outputs Open, Twenty Bits Toggling, OE=GND LE = VCC VIN=VCC or VIN=GND — 3.0 5.5[12] VIN=3.4V or VIN=GND — 8.0 20.5[12] Notes: 9. Per TTL driven input (VIN=3.4V); all other inputs at VCC or GND. 10. This parameter is not directly testable, but is derived for use in Total Power Supply calculations. 11. 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. 12. Values for these conditions are examples of the ICC formula. These limits are specified but not tested. |
