OL

 = 48mA (commercial), 32mA (military)

• CMOS power levels (1mW typ. static)

• Substantially lower input current levels than AMD’s

bipolar (5

µ

A typ.)

• TTL input and output level compatible

• CMOS output level compatible

• Manufactured using advanced CMOS processing

• Available in 300 mil plastic and hermetic DIP, as well as

LCC, SOIC and CERPACK

• Product available in Radiation Tolerant and Radiation

Enhanced versions

• Military product compliant to MIL-STD-883, Class B

DESCRIPTION:

The IDT29FCT520A/B/C contains 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.

In the IDT29FCT520A/B/C 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.  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.
