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.

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-
INGS may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions
above those indicated in the operational sections of this specification is
not implied. Exposure to absolute maximum rating conditions for
extended periods may affect reliability. No terminal voltage may exceed
VCC by +0.5V unless otherwise noted.
2. Input and VCC terminals only.
3. Outputs and I/O terminals only.
