# IC
= ICC + ICC × DH × NT + ICCD (f0/2 + f1 × N1)
Where:
IC
= Total supply current
ICC
= Power-supply current with CMOS input levels
ICC = Power-supply current for a TTL high input (VIN = 3.4 V)
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 milliamperes and all frequencies are in megahertz.
|| Values for these conditions are examples of the ICC formula.
