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
The IDT29FCT520A/B/C contains four 8-bit positive edgetriggered 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.

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. 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
