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 RATINGS 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.
