VIN = 3.4V (3) 0.5 2.5 mA Input @ TTL HIGH ICCD Supply Current per VCC = Max., VIN = VCC 60 100 µA/ Input per MHz (4) Outputs Open VIN = GND MHz OE1 = OE2 = GND One Input Toggling 50% Duty Cycle IC Total Power Supply VCC = Max., VIN = VCC 0.6 1.5 (5) mA Current (6) Outputs Open VIN = GND fCP = 10 MHZ 50% Duty Cycle VIN = 3.4V 0.9 2.3 (5) OE1 = OE2 = GND VIN = GND fI = 5 MHZ One Bit Toggling VCC = Max., VIN = VCC 3.0 5.5 (5) Outputs Open VIN = GND fCP = 10 MHZ 50% Duty Cycle VIN = 3.4 8.0 20.5 (5) OE1 = OE2 = GND VIN = GND Eight Bits Toggling fI = 2.5 MHZ 50% Duty Cycle Notes: 1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device. 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 + ∆ICC DHNT + ICCD (fCP/2 + fINI) ICC = Quiescent Current ∆ICC = 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). fI = Input Frequency NI = Number of Inputs at fI All currents are in milliamps and all frequencies are in megahertz. |
