MULTILEVEL PIPELINE REGISTER
Integrated Device Technology, Inc.
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 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.
