DESCRIPTION:
IDT29FCT520AT/BT/CT/DT IDT29FCT521AT/ BT/CT/DT each contain four 8-bit positive edge-triggered registers. These operated dual 2-level single 4-level pipeline. single 8-bit input provided four registers available 8-bit, 3-state output. These devices differ only data loaded into between registers 2-level operation. difference illustrated Figure IDT29FCT520AT/BT/CT/DT when data entered into first level existing data first level moved second level. IDT29FCT521AT/BT/CT/DT, these instructions simply cause data first level overwritten. Transfer data second level achieved using 4-level shift instruction This transfer also causes first level change. either part hold.
