4 / 6 page  CY74FCT163952 CY74FCT163H952 4 Power Supply Characteristics Parameter Description Test Conditions Typ.[7] Max. Unit ICCD Dynamic Power Supply Current[13] VCC=Max., One Input Toggling, 50% Duty Cycle, Outputs Open, OE=GND VIN=VCC or VIN=GND 50 75 µA/MHz IC Total Power Supply Current[14] VCC=Max., f1=10 MHz, 50% Duty Cycle, Outputs Open, One Bit Toggling, OE=GND VIN=VCC or VIN=GND 0.5 0.8 mA VIN=VCC–0.6V or VIN=GND 0.5 0.8 mA VCC=Max., f1=2.5 MHz, 50% Duty Cycle, Outputs Open, Six- teen Bits Toggling, OE=GND VIN=VCC or VIN=GND 2.0 3.0[15] mA VIN=VCC–0.6V or VIN=GND 2.0 3.3[15] mA Switching Characteristics Over the Operating Range VCC=3.0V to 3.6V [16,17] Parameter Description CY74FCT163952A CY74FCT163952C CY74FCT163H952C Min. Max. Min. Max. Unit Fig. No.[18] tPLH tPHL Propagation Delay Data to Output 1.5 4.8 1.5 4.4 ns 1, 3 tPZH tPZL Output Enable Time 1.5 6.2 1.5 5.8 ns 1, 7, 8 tPHZ tPLZ Output Disable Time 1.5 5.6 1.5 5.2 ns 1, 7, 8 tSK(O) Output Skew[19] 0.5 0.5 ns — Notes: 13. This parameter is not directly testable, but is derived for use in Total Power Supply calculations. 14. IC =IQUIESCENT + IINPUTS + IDYNAMIC IC =ICC+∆ICCDHNT+ICCD(f0/2 + f1N1) ICC = Quiescent Current with CMOS input levels ∆I CC = 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) f0 = Clock frequency for registered devices, otherwise zero f1 = Input signal frequency N1 = Number of inputs changing at f1 All currents are in milliamps and all frequencies are in megahertz. 15. Values for these conditions are examples of the ICC formula. These limits are specified but not tested. 16. Minimum limits are specified but not tested on Propagation Delays. 17. For VCC =2.7, propagation delay, output enable and output disable times should be degraded by 20%. 18. See “Parameter Measurement Information” in the General Information section. 19. Skew between any two outputs of the same package switching in the same direction. This parameter is ensured by design.
