For conditions shown as Max. or Min., 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 + ∆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. 2613 tbl 08 |
