Product Description:
Pericom Semiconductor’s PI29FCT series of logic circuits are pro-duced in the Company’s advanced 0.8 micron CMOS technology, achieving industry leading speed grades.
The PI29FCT520T/2520T and PI29FCT521T are multilevel pipeline registers containing four 8-bit positive triggered registers which can be configured as a dual 2-level or a single 4-level pipeline. These products are designed for use as temporary storage or for storage delays in pipelined systems.

Product Features:
• PI29FCT520T and PI29FCT521T are pinout and function compatible with IDT29FCT520/521, QS29FCT520/521 and AMDs Am29520/521
• Four 8-bit high-speed registers
• Hold, Transfer, and load instructions
• Dual two-level or single four-level pipeline operation
• TTL input and output levels, reducing problematic "ground bounce"
• High output drive IOL = 48 mA
• Extremely low static power (1 mW, typ.)
• Industrial operating temperature range: –40°C to +85°C
• FCT (2xxxT) has a 25Ω series resistor.
• Packages available:
