DESCRIPTION:
The IDT29FCT520AT/BT/CT/DT and IDT29FCT521AT/
BT/CT/DT each contain four 8-bit positive edge-triggered
registers. These may be operated as a dual 2-level or as a
single 4-level pipeline. A single 8-bit input is provided and any
of the four registers is available at the 8-bit, 3-state output.
These devices differ only in the way data is loaded into and
between the registers in 2-level operation. The difference is
illustrated in Figure 1. In the IDT29FCT520AT/BT/CT/DT
when data is entered into the first level (I = 2 or I = 1), the
existing data in the first level is moved to the second level. In
the IDT29FCT521AT/BT/CT/DT, these instructions simply
cause the data in the first level to be overwritten. Transfer of
data to the second level is achieved using the 4-level shift
instruction (I = 0). This transfer also causes the first level to
change. In either part I=3 is for hold.
