Units ICC Quiescent Power Supply Current VCC = Max. VIN = GND or VCC — 0.1 30 µA ΔICC Supply Current per Inputs @ TTL HIGH VCC = Max. VIN = VCC – 0.6V(3) — 47 300 ICCD Supply Current per Input per MHz(4) VCC = Max., Outputs Open Per Output Toggling 50% Duty Cycle VIN = VCC — mA/ VIN = GND 0.08 0.16 MHz 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 (VIN = VCC – 0.6V); 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 IC formula. These limits are guaranteed but not tested. Capacitance (TA = 25°C, f = 1 MHz) Parameters(1) Description Test Conditions Typ Max. Units CIN Input Capacitance VIN = 0V 3.0 4 pF COUT Output Capacitance VOUT = 0V 6 Notes: 1. This parameter is determined by device characterization but is not production tested. Notes: 1. Other loading condition is described on page 4, “Test Circuits for All Outputs.” 2. These parameters are guaranteed by design. 3. Minimum propagation delay of 1.5ns is guaranteed by design. Maximum Switching Characteristics (Over operating range) Symbol Description Condition Max. Units tPLH tPHL Propagation Delay A to Bn(3) CL =15pF 2.5 ns tR/tF Rise/Fall Time(2) 0.8V –2.0V 1.5 tSK(p) Pulse Skew (same pkg)(1,2) CL =15pF 0.35 tSK(o) Output Skew (same pkg.)(1,2) 0.2 tSK(t) Output Skew (different pkg.)(1,2) 0.55 FIN Input Frequency(1,2) 133 MHz |
