NOTES:
3267 tbl 08
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics.
2. Typical values are at VCC = 3.3V, +25°C ambient.
3. Per TTL driven input; all other inputs at VCC or GND.
4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations. It is derived with Q frequency as the reference.
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 + ∆ICC DHNT + ICCD (f) + ILOAD
ICC = Quiescent Current (ICCL, ICCH and ICCZ)
∆ICC = Power Supply Current for a TTL High Input
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)
f = SYNC input frequency
ILOAD = Dynamic Current due to load.
