NOTES:

1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.

2. Typical values are at VCC = 2.5V, +25°C ambient.

3. This parameter is not directly testable, but is derived for use in Total Power Supply calculations.

4. IC = IQUIESCENT + IINPUTS + IDYNAMIC

IC = ICC + ∆ICC DHNT + ICCD (fi)

ICC = Quiescent Current (ICCL, ICCH and ICCZ)

∆ICC = Power Supply Current for a TTL High Input (VIN = VCC -0.6V)

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)

fi = Input Frequency
