NOTES:
1. For conditions shown as Min. or Max., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC1 = 5V, VCC2 = 3.3V, +25°C ambient.
3. Per TTL driven input. 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 = ICC1 + ICC2 + ΔICC DHNT + ICCD (fCPNCP/2 + fiNi)
ICC1 = Quiescent Current (ICC1L, ICC1H and ICC1Z)
ICC2 = Quiescent Current (ICC2L, ICC2H and ICC2Z)
ΔICC = Power Supply Current for a TTL High Input
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)
NCP = Number of Clock Inputs at fCP
fi = Input Frequency
Ni = Number of Inputs at fi
