DESCRIPTION:The IDT29FCT520AT/BT/CT/DT and IDT29FCT521AT/BT/CT/DT each contain four 8-bit positive edge-triggeredregisters. These may be operated as a dual 2-level or as asingle 4-level pipeline. A single 8-bit input is provided and anyof the four registers is available at the 8-bit, 3-state output.These devices differ only in the way data is loaded into andbetween the registers in 2-level operation. The difference isillustrated in Figure 1. In the IDT29FCT520AT/BT/CT/DTwhen data is entered into the first level (I = 2 or I = 1), theexisting data in the first level is moved to the second level. Inthe IDT29FCT521AT/BT/CT/DT, these instructions simplycause the data in the first level to be overwritten. Transfer ofdata to the second level is achieved using the 4-level shiftinstruction (I = 0). This transfer also causes the first level tochange. In either part I=3 is for hold.
