74FCT3807PYG

Overview

The Renesas Electronics Corporation 74FCT3807PYG is a single-input, ten-output clock buffer and driver belonging to the 74FCT series. It accepts LVTTL input signals and provides CMOS/TTL outputs. The device operates within a supply voltage range of 3V to 3.6V and supports maximum frequencies up to 100 MHz. It is housed in a 20-SSOP package with dimensions of 0.209 inches (5.30mm) width. The component is designed for surface mount installation and functions across an operating temperature range of -40°C to 85°C.

Feature Summary

• Single-to-ten fan-out buffering capability
• LVTTL input interface with CMOS/TTL output compatibility
• Maximum operating frequency of 100 MHz
• Wide industrial temperature range from -40°C to 85°C

Applications

• Clock distribution networks requiring high fan-out
• System timing synchronization in digital circuits
• Signal buffering for LVCMOS/LVTTL logic families

Procurement Notes

Verify current availability status as the 74FCT3807PYGI variant is listed as obsolete with an End-of-Life notification dated May 30, 2025. Confirm package type and suffix requirements against specific design needs, as variations such as PYGI8 or QG exist with different packaging and temperature ratings. Cross-reference datasheet IDT74FCT3807/A for final electrical specifications before procurement.

Selection Notes

Select this component when a 1:10 clock split is required with LVTTL inputs. Ensure the design environment supports the -40°C to 85°C temperature range. Compare against the 74FCT3807QG if a higher 166 MHz frequency is needed, noting its narrower commercial temperature range. Verify that the 20-SSOP footprint matches the PCB layout constraints.

Part Context

This part belongs to the broader 74FCT3807 family, which includes variants like 74FCT3807APYG8 and 74FCT3807EPYG. These components share similar core functionalities but differ in packaging formats (SSOP, QSOP), temperature grades, and production statuses. The 74FCT3807PYG specifically targets industrial applications requiring robust thermal performance.

Replacement Considerations

Publicly confirmed substitutes include PI49FCT3807CQE by Diodes Incorporated and 5PB1106PGGI by Renesas. Note that the original 74FCT3807PYGI is marked as obsolete.
