Typ (2) Max. Units ICC Quiescent Power VCC = Max. VIN = GND or VCC —3 30 µA Supply Current ∆I CC Supply Current per VCC = Max. VIN = VCC – 0.6V (3) — 2.0 300 µA Inputs @ TTL HIGH ICCD Supply Current per VCC = Max., VIN = VCC — 0.08 0.16 mA/ Input per MHz (4) Outputs Open VIN = GND MHZ OEA or OEB = GND Per Output Toggling 50% Duty Cycle IC Total Power Supply VCC = Max., VIN = VCC — 3.3 9.0(5) Current(6) Outputs Open VIN=GND fO = 10 MHZ 50% Duty Cycle VIN = VCC – 0.6V — 3.3 10.0(5) OEA or OEB = GND VIN = GND Mon. Outputs Toggling mA VCC = Max., VIN = VCC — 1.8 6.0(5) Outputs Open VIN = GND fO = 2.5 MHZ 50% Duty Cycle VIN = VCC – 0.6V — 1.8 7.0(5) OEA or OEB = GND VIN = GND Eleven Outputs Toggling Notes: 1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device. 2. Typical values are at VCC = 3.3V, +25°C ambient. 3. Per TTL driven input (VIN = VCC 0.6V); 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 IC formula. These limits are guaranteed but not tested. 6. IC = IQUIESCENT + IINPUTS + IDYNAMIC IC = ICC + ∆ICC DHNT + ICCD (fONO) ICC = Quiescent Current ∆ICC = Power Supply Current for a TTL High Input (VIN = VCC 0.6V) 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) fO = Output Frequency NO = Number of Outputs at fO All currents are in milliamps and all frequencies are in megahertz. |
