Notes:
10. Per TTL driven input (VIN=3.4V); all other inputs at VCC or GND.
11. This parameter is not directly testable, but is derived for use in Total Power Supply calculations.
12. IC
=IQUIESCENT + IINPUTS + IDYNAMIC
IC
=ICC+∆ICCDHNT+ICCD(f0/2 + f1N1)
ICC = Quiescent Current with CMOS input levels
∆I
CC = 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)
f0
= Clock frequency for registered devices, otherwise zero
f1
= Input signal frequency
N1
= Number of inputs changing at f1
All currents are in milliamps and all frequencies are in megahertz.
13. Values for these conditions are examples of the ICC formula. These limits are specified but not tested.
