IDT74FCT20807PYI

Clock Buffers, Drivers Overview

The IDT74FCT20807PYI is a 1-to-10 fanout, non-inverting clock buffer designed for 2.5V CMOS applications within the industrial temperature range (-40°C to +85°C). It operates at frequencies up to 150 MHz with a maximum propagation delay of 3.5 ns and output skew under 150 ps. The device features TTL-compatible inputs and outputs, low input capacitance (3 pF typical), and multiple power/ground pins to minimize noise. It is housed in a 20-pin Shrink Small Outline Package (SSOP) and requires a 2.5V supply voltage.

Clock Buffers, Drivers Feature Summary

• High-frequency operation exceeding 150 MHz with propagation delay less than 3 ns
• Guaranteed low output-to-output skew of less than 150 ps
• Very low duty cycle distortion under 300 ps
• TTL compatible inputs and outputs with 2.5V supply voltage

Clock Buffers, Drivers Applications

• Clock distribution networks in synchronous systems
• Signal distribution requiring high fanout
• Low noise clock buffering for 2.5V CMOS circuits

Clock Buffers, Drivers Procurement Notes

Verify component status as End-of-Life (EOL) for non-green parts occurred on May 13, 2010. Confirm RoHS compliance and package type (SSOP vs QSOP) when sourcing replacements. Check manufacturer documentation for current availability and alternative part numbers.

Clock Buffers, Drivers Selection Notes

Select this component for 2.5V systems requiring 1:10 clock fanout. Ensure load capacitance matches test conditions (12pF or 22pF) for accurate timing analysis. Verify thermal requirements for the industrial temperature range. Consider air flow recommendations for frequencies above 133 MHz.

Clock Buffers, Drivers Part Context

Part of the FCT20807 series, which provides high-speed, low-noise clock buffering. The 'PY' suffix indicates the Shrink Small Outline IC (SSOP) package variant. This series serves as a replacement for older ABT functions with improved speed and lower power consumption.

Clock Buffers, Drivers Replacement Considerations

Check for green-compliant alternatives if non-green parts are obsolete. Compare pinouts and electrical characteristics with other 1-to-10 clock drivers in the 2.5V FCT family. Verify package compatibility for direct footprint substitution.
