NOTES:
1. 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 from ICCD1 for use in Total Power Supply calculations.
5. Total power supply current is calculated as follows:
IC = IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC +
ICC DHNT + ICCD (fCP + 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 Output 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.
6. This parameter is not production tested but is an indicator of the power dissipated with outputs loaded.
7. Values for these conditions are examples of the IC formula in note 5 above. These are guaranteed but not tested.
