DC ELECTRICAL CHARACTERISTICS OVER OPERATING RANGE
FollowingConditionsApplyUnlessOtherwiseSpecified:
Industrial: TA = –40°C to +85°C, VCC = 5.0V ±5%
NOTES:
1. Typical values are at VCC = 5.0V, TA = 25°C.
2. This parameter is measured at characterization but not tested.
3. ROUT changed on March 8, 2002. See rear page for more information.

NOTES:
1. For conditions shown as Min. or Max., use the appropriate values specified under DC Electrical Characteristics.
2. Per TLL driven input (VIN = 3.4V).
3. For flip-flops, ICCD is measured by switching one of the data input pins so that the output changes every clock cycle. This is a measurement of device power consumption
only and does not include power to drive load capacitance or tester capacitance.
4. 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 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.
