Notes:
1.
For Max. or Min. conditions, use appropriate value specied under Electrical Characteristics for the applicable device.
2.
Typical values are at VCC = 5.0V, +25°C ambient.
3.
Per TTL driven input (VIN = 3.4V); all other inputs at VCC or GND.
4.
Guaranteed by design, not production tested.
5.
Values for these conditions are examples of the ICC formula. These limits are guaranteed but not tested.
6.
IC =IQUIESCENT + IINPUTS + IDYNAMIC
IC = ICC + ΔICC DHNT + ICCD (fCP/2 + fINI)
ICC = Quiescent Current
ΔICC = 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 megahertz.
Notes:
1.
For Max. or Min. conditions, use appropriate value specied under Electrical Characteristics for the applicable device.
2.
Typical values are at VCC = 5.0V, +25°C ambient.
