74FCT3807DPYGI8

Overview

The Renesas Electronics 74FCT3807DPYGI8 is a high-speed clock driver and distribution component belonging to the 74FCT3807D series. It functions as a 1:10 fan-out buffer, accepting a single TTL-compatible input and providing ten CMOS/TTL outputs. The device operates within a supply voltage range of 3 V to 3.6 V and supports maximum output frequencies up to 166 MHz. Packaged in a 20-pin SSOP format for surface mount installation, this integrated circuit is designed for efficient clock signal propagation in digital systems.

Feature Summary

• 1:10 Clock Distribution Ratio
• Maximum Output Frequency of 166 MHz
• Supply Voltage Range: 3 V to 3.6 V
• TTL Input with CMOS/TTL Outputs

Applications

• Clock signal distribution in high-speed digital circuits
• Buffering clock sources for multiple synchronous loads
• System timing architecture in industrial or commercial equipment

Procurement Notes

This specific part number (74FCT3807DPYGI8) is officially listed as End-of-Life (EOL). Distributors indicate that it is no longer actively sold in certain regions. Verification of current availability requires checking authorized channels for remaining stock or obsolete inventory, as standard production has ceased.

Selection Notes

Designers should note that the 'D' suffix in the part number typically denotes an extended temperature range compared to standard variants. When selecting replacements, verify that the substitute component matches the 166 MHz frequency capability and the 20-SSOP package dimensions to ensure physical compatibility.

Part Context

The 74FCT3807 family consists of various clock drivers with different packaging options such as SOIC, QSOP, and SSOP. The DPYGI8 variant specifically utilizes the SSOP-20 package. Other family members include the 74FCT3807QG and 74FCT3807PYG8, which may offer similar electrical performance but differ in thermal ratings or physical footprint.

Replacement Considerations

Public records list the 5PB1106PGGI8 as a potential replacement from Renesas. Designers must verify pinout compatibility and electrical specifications against the original datasheet before substitution.
