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 = 5.0V, +25 °C ambient. 3. Not more than one output should be shorted at one time. Duration of the short circuit test should not exceed one second. 4. The test limit for this parameter is ±5µA at TA = –55°C. 5. This parameter is guaranteed but not tested. POWER SUPPLY CHARACTERISTICS 2634 tbl 08 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 = 5.0V, +25 °C ambient. 3. Per TTL driven input (VIN = 3.4V). All other inputs at VCC or GND. 4. This parameter is not directly testable, but is derived for use in Total Power Supply Calculations. 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 (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 megahertz.
