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 N T = 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. |
