74FCT807CTSOGI8

Overview

The 74FCT807CTSOGI8 is a clock fan-out buffer manufactured by Renesas Electronics. It provides a 1:10 input-to-output ratio, distributing a single TTL input signal to ten TTL outputs. The device operates within a supply voltage range of 4.75V to 5.25V and supports maximum frequencies up to 100 MHz. Packaged in a 20-SOIC (0.295", 7.50mm wide) surface-mount format, it is designed for industrial applications with an operating temperature range of 0°C to 70°C. This component belongs to the 74FCT series and is currently classified as obsolete.

Feature Summary

• Single-input, ten-output clock distribution architecture
• TTL-compatible input and output logic levels
• Maximum operating frequency of 100 MHz
• Standard 20-SOIC surface-mount package

Applications

• Clock distribution networks requiring TTL signaling
• System timing synchronization in industrial equipment
• Digital circuit board clock buffering

Procurement Notes

This part number is officially listed as obsolete or discontinued by the manufacturer. Availability is restricted to existing stock or surplus channels. Verification of authenticity and storage history is critical when sourcing from third-party distributors due to the end-of-life status.

Selection Notes

Engineers replacing this component should consider the 74FCT3807 series for modern designs. The 74FCT3807 variants offer similar 1:10 distribution but operate at lower 3.3V voltages and often include extended temperature ranges. Ensure that the target system's I/O voltage levels are compatible with the replacement device before substitution.

Part Context

The 74FCT807CTSOGI8 is part of the broader 74FCT family of high-speed CMOS logic devices. The 'CT' suffix typically denotes specific packaging or tape-and-reel configurations within the SOIC-20 footprint. As a legacy product, it represents earlier generations of clock drivers used in systems transitioning from older TTL standards to faster CMOS technologies.
