4 x 8-bit Multilevel Pipeline Register
DESCRIPTION
The L29C520 and L29C521 are pinfor-pin compatible with the IDT29FCT520/IDT29FCT521 and AMD Am29520/Am29521, implemented in low power CMOS. 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, I1-0, control the loading of the registers. For either device, the registers may be configured 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, I1-0 may be set to prevent any register from changing. The S1-0 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.

Setup time, for example, is specified as a minimum since the external system must supply at least that much time to meet the worst-case requirements 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. 1. Maximum Ratings indicate stress specifications only. Functional operation of these products at values beyond those indicated in the Operating Conditions table is not implied. Exposure to maximum rating conditions for extended periods may affect reliability. 11. For the tENA 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 voltage, VTH, is set at 3.5 V for Z-to-0 and 0-to-Z tests, and set at 0 V for Zto-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.
