Unit ΔICC Quiescent Power Supply Current VCC = Max. — 0.5 1.5 mA TTL Inputs HIGH VIN = 3.4V(3) ICCD Dynamic Power Supply VCC = Max. VIN = VCC — 60 100 µA/ Current(4) Outputs Open VIN = GND MHz x OE = GND One Input Toggling 50% Duty Cycle IC Total Power Supply Current(6) VCC = Max. VIN = VCC — 0.6 1.5 mA Outputs Open VIN = GND fi = 10MHz 50% Duty Cycle VIN = 3.4V — 0.9 2.3 x OE = GND VIN = GND One Bit Toggling VCC = Max. VIN = VCC — 2.4 4.5(5) Outputs Open VIN = GND fi = 2.5MHz 50% Duty Cycle VIN = 3.4V — 6.4 16.5(5) x OE = GND VIN = GND Sixteen Bits Toggling NOTES: 1. For conditions shown as Min. or Max., use appropriate value specified under Electrical Characteristics for the applicable device type. 2. Typical values are at VCC = 5.0V, +25°C ambient. 3. Per TTL driven input (VIN = 3.4V). All other inputs at VCC or GND. 4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations. 5. Values for these conditions are examples of the ICC formula. These limits are guaranteed but not tested. 6. IC = IQUIESCENT + IINPUTS + IDYNAMIC IC = ICC + ΔICC DHNT + ICCD (fCPNCP/2 + fiNi) ICC = Quiescent Current (ICCL, ICCH and ICCZ) ΔICC = 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) fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices) NCP = Number of Clock Inputs at fCP fi = Input Frequency Ni = Number of Inputs at fi POWER SUPPLY CHARACTERISTICS |
