5 / 9 page PI74FCT16244T/162244T 16-Bit Buffer/Line Drivers 5 PS2031L 02/26/07 Power Supply Characteristics Parameters Description Test Conditions (1) Min. Typ (2) Max. Units ICC Quiescent Power VCC = Max. VIN = GND or VCC 0.1 500 μA Supply Current ΔICC Supply Current per VCC = Max. VIN = 3.4V(3) 0.5 1.5 mA Input @ TTL HIGH ICCD Supply Current per VCC = Max., VIN = VCC 60 100 μA/ Input per MHz(4) Outputs Open VIN = GND MHz X OE = GND One Bit Toggling 50% Duty Cycle IC Total Power Supply VCC = Max., VIN = VCC 0.6 1.5(5) mA Current(6) Outputs Open VIN = GND fI = 10 MHZ 50% Duty Cycle X OE = GND One Bit Toggling VIN = 3.4V 0.9 2.3(5) VIN = GND VCC = Max., VIN = VCC 2.4 4.5(5) Outputs Open VIN = GND fI = 2.5 MHZ 50% Duty Cycle X OE = GND 16 Bits Toggling VIN = 3.4V 6.4 16.5(5) VIN = GND Notes: 1. For Max. or Min. conditions, use appropriate value specified 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. 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 + 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. 07-0059 |
