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 (5A 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 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.

NOTES: 2620 tbl 03 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. Inputs and VCC terminals. 3.
