74FCT807CTSOG8

Overview

The 74FCT807CTSOG8 is a clock fan-out buffer and distribution integrated circuit manufactured by Renesas Electronics Corporation. It features a single input to ten output configuration with TTL-compatible inputs and outputs. The device operates within a supply voltage range of 4.75V to 5.25V and supports maximum frequencies up to 100MHz. Packaged in a 20-SOIC (0.295", 7.50mm wide) surface-mount housing, it is designed for high-speed clock signal distribution. The component is currently classified as obsolete or not recommended for new designs.

Feature Summary

• 1:10 Clock Fan-Out Buffer with TTL Input/Output compatibility
• Maximum operating frequency of 100 MHz
• Supply voltage range of 4.75V to 5.25V
• Surface-mount 20-SOIC package

Applications

• High-speed clock distribution in digital systems
• Buffering clock signals for multiple synchronous loads
• TTL-compatible logic interface circuits

Procurement Notes

This component is listed as obsolete or discontinued by the manufacturer. Availability is limited to existing stock from third-party distributors. Verification of authenticity and storage history is critical due to the end-of-life status. Buyers should confirm the specific manufacturing date code and ensure compliance with RoHS directives as indicated in official documentation before procurement.

Selection Notes

Designers requiring this functionality should consider modern equivalents from the 74FCT series or alternative manufacturers offering active production. Verify that replacement parts maintain the same 1:10 ratio, 100MHz speed, and 20-SOIC footprint. Check for any changes in pinout or electrical characteristics such as drive strength and propagation delay when substituting obsolete components.

Part Context

The 74FCT807CTSOG8 belongs to the 74FCT family of Fast CMOS logic devices, which bridge the performance gap between standard CMOS and TTL logic. This specific part number denotes the commercial temperature grade (C) and the SOIC-20 tape-and-reel packaging variant. It is functionally equivalent to other variants like the 74FCT807BT and IDT74FCT807CT.

Replacement Considerations

Publicly confirmed substitute part numbers include IDT74FCT807CT and generic equivalents within the 74FCT807 family. Cross-reference with current Renesas or IDT product lines for actively manufactured clock drivers with identical pinouts and specifications.
