08/16/2000–LDS.381-P8 1. Maximum Ratings indicate stress specifications only. Functional oper- ation of these products at values beyond those indicated in the Operating Condi- tions table is not implied. Exposure to maximum rating conditions for ex- tended periods may affect reliability. 2. The products described by this spec- ification include internal circuitry de- signed to protect the chip from damag- ing substrate injection currents and ac- cumulations of static charge. Neverthe- less, conventional precautions should be observed during storage, handling, and use of these circuits in order to avoid exposure to excessive electrical stress values. 3. This device provides hard clamping of transient undershoot and overshoot. In- put levels below ground or above V CC will be clamped beginning at –0.6 V and VCC + 0.6 V. The device can withstand indefinite operation with inputs in the range of –0.5 V to +7.0 V. Device opera- tion will not be adversely affected, how- ever, input current levels will be well in excess of 100 mA. 4. Actual test conditions may vary from those designated but operation is guar- anteed as specified. 5. Supply current for a given applica- tion can be accurately approximated by: where N = total number of device outputs C = capacitive load per output V = supply voltage F = clock frequency 6. Tested with all outputs changing ev- ery cycle and no load, at a 5 MHz clock rate. 7. Tested with all inputs within 0.1 V of V CC or Ground, no load. 8. These parameters are guaranteed but not 100% tested. NCV F NOTES 9. AC specifications are tested with input transition times less than 3 ns, output reference levels of 1.5 V (except t DIS test), and input levels of nominally 0 to 3.0 V. Output loading may be a resistive divider which provides for specified IOH and IOL at an output voltage of VOH min and VOL max respectively. Alternatively, a diode bridge with upper and lower current sources of IOH and IOL respectively, and a balancing voltage of 1.5 V may be used. Parasitic capacitance is 30 pF minimum, and may be distributed. This device has high-speed outputs ca- pable of large instantaneous current pulses and fast turn-on/turn-off times. As a result, care must be exercised in the testing of this device. The following measures are recommended: a. A 0.1 µF ceramic capacitor should be installed between V CC and Ground leads as close to the Device Under Test (DUT) as possible. Similar capacitors should be installed between device VCC and the tester common, and device ground and tester common. b. Ground and VCC supply planes must be brought directly to the DUT socket or contactor fingers. c. Input voltages should be adjusted to compensate for inductive ground and VCC noise to maintain required DUT input levels relative to the DUT ground pin. 10. Each parameter is shown as a min- imum or maximum value. Input re- quirements are specified from the point of view of the external system driving the chip. Setup time, for example, is specified as a minimum since the exter- nal system must supply at least that much time to meet the worst-case re- quirements of all parts. Responses from the internal circuitry are specified from the point of view of the device. Output delay, for example, is specified as a maximum since worst-case operation of any device always provides data within that time. 11. For the t ENA test, the transition is measured to the 1.5 V crossing point with datasheet loads. For the tDIS test, the transition is measured to the ±200mV level from the measured steady-state output voltage with ±10mA loads. The balancing volt- age, V TH, is set at 3.5 V for Z-to-0 and 0-to-Z tests, and set at 0 V for Z- to-1 and 1-to-Z tests. 12. These parameters are only tested at the high temperature extreme, which is the worst case for leakage current.

08/16/2000–LDS.381-P9 C ASCADING THE L4C381 (of the C0 setup time, if the F register is used). The sum gives the overall input-to-output delay (or setup time) for the 32-bit configuration. This method gives a conservative result, since the C 16 output is very lightly loaded. Formulas for calculation of all critical delays for a 32-bit system are shown in Figures 4A through 4D. Cascading to greater than 32 bits can be accomplished in two ways: The simplest (but slowest) method is to simply connect the C16 output of each slice to the C0 input of the next more significant slice. Propagation delays are calculated as for the 32-bit case, except that the C 0 to C16 delays for all intermediate slices must be added to the overall delay for each path. A faster method is to use an external carry-lookahead generator. The P and G outputs of each slice are connected as inputs to the CLA generator, which in turn produces the C 0 inputs for each slice except the least significant. The C 16 outputs are not used in this case, except for the most significant one, which is the carry out of the overall system. The carry in to the system is connected to the C 0 input of the least significant slice, and also to the carry lookahead generator. Propagation delays for this configura- tion are the sum of the time to P, G, for the least significant slice, the propagation delay of the carry look- ahead generator, and the C 0 to output time of the most significant slice. Cascading the L4C381 to 32 bits is accomplished simply by connecting the C16 output of the least significant slice to the C0 input of the most sig- nificant slice. The S2-S0, OSA, OSB, ENA, ENB, and ENF lines are common to both devices. The Zero output flags should be logically ANDed to produce the Zero flag for the 32-bit result. The OVF and C outputs of the most significant slice are valid for the 32-bit result. Propagation delay calculations for this configuration require two steps: First determine the propagation delay from the input of interest to the C 16 output of the lower slice. Add this number to the delay from the C0 input of the upper slice to the output of interest
