PIPELINE REGISTER
IDT29FCT520A
IDT29FCT520B
IDT29FCT520C
FEATURES:
• 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.)
• 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.

NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Per TTL driven input (VIN = 3.4V); all other inputs at VCC or GND.
4. This parameter is not directly testable, but is derived for use in Total Power Supply calculations.
5. Values for these conditions are examples of the ICC formula. These limits are guaranteed but not tested.
6. IC = IQUIESCENT +IINPUTS + IDYNAMIC
IC = ICC + ICC DHNT + ICCD (fCP/2 + fiNi)
ICC = Quiescent Current
ICC = Power Supply Current for a TTL HIgh Input (VIN = 3.4V)
DH = Duty Cycle for TTL Inputs High
NT = Number of TTL inputs at DH
ICCD = Dynamic Current Caused by an Input Transition Pair (HLH or LHL)
fCP = Clock Frequency for Register Devices (Zero for Non-Register Devices)
fi = Input Frequency
Ni = Number of Inputs at fi
All currents are in milliamps and all frequencies are in megahertz.
