NOTES:
1. For conditions shown as max. or min., use appropriate VCC value.
2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Not more than one output should be shorted at a time. Duration of the short circuit test should not exceed one second.
4. Per TTL driven input (VIN = 3.4V); all other inputs at VCC or GND.
5. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations.
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 megaherz.
