The L29C520 and L29C521 contain four registers which can be configured as two independent, 2-level pipelines or as one 4-level pipeline. The Instruction pins, I 1-0, control the loading of the registers. For either device, the registers may be config- ured as a four-stage delay line, with data loaded into R1 and shifted sequentially through R2, R3, and R4. Also, for the L29C520, data may be loaded from the inputs into either R1 or R3 with only R2 or R4 shifting. The L29C521 differs from the L29C520 in that R2 and R4 remain unchanged during this type of data load, as shown in Tables 1 and 2. Finally, I 1-0 may be set to prevent any register from changing. The S 1-0 select lines control a 4-to-1 multiplexer which routes the contents of any of the registers to the Y output pins. The independence of the I and S controls allows simultaneous write and read operations on different registers. S1 S0 Register Selected L L Register 4 L H Register 3 H L Register 2 H H Register 1

4 x 8-bit Multilevel Pipeline Register Pipeline Registers 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.
