Integrated Device Technology, Inc.
FEATURES:
DESCRIPTION:
• Equivalent to AMD’s Am29520 bipolar Multilevel Pipeline
Register in pinout/function, speed and output drive over
full temperature and voltage supply extremes
• Four 8-bit high-speed registers
• Dual two-level or single four-level push-only stack
operation
• All registers available at multiplexed output
• Hold, transfer and load instructions
• Provides temporary address or data storage
• IOL = 48mA (commercial), 32mA (military)
• CMOS power levels (1mW typ. static)
• Substantially lower input current levels than AMD’s
bipolar (5µA typ.)
TheIDT29FCT520A/B/Ccontainsfour8-bitpositive 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.
