4 / 7 page PI74LPT16373 3.3V 16-Bit Transparent Latch 4 PS2069D 06/05/06 Power Supply Characteristics Parameters Description Test Conditions(1) Min. Typ(2) Max. Units ICC Quiescent Power Supply Current VCC = Max. VIN = GND or VCC 0.1 10 µA ∆ICC Quiescent Power Supply Current TTL Inputs HIGH VCC = Max. VIN = VCC – 0.6V(3) 500 ICCD Dynamic Power Supply(4) VCC = Max., Outputs Open X OE = GND xLE = Vcc One Bit Toggling 50% Duty Cycle VIN = VCC VIN = GND 50 75 µA/ MHz IC Total Power Supply Current(6) VCC = Max., Outputs Open fI = 10 MHZ 50% Duty Cycle X OE = GND One Bit Toggling VIN = VCC – 0.6V VIN = GND 0.6 X LE = VCC 2.3 mA VCC = Max., Outputs Open fI = 2.5 MHZ 50% Duty Cycle X OE = GND 16 Bits Toggling VIN = VCC – 0.6V VIN = GND 2.1 X LE = VCC 4.7(5) Notes: 1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device. 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. 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 (ICCL, ICCH and ICCZ) ΔICC = 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) fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices) NCP = Number of Clock Inputs at fCP fI = Input Frequency NI = Number of Inputs at fI All currents are in milliamps and all frequencies are in megahertz. 06-0210 |
