74FCT807CTSOG

Overview

The Renesas Electronics Corporation 74FCT807CTSOG is a single-channel clock driver and distribution buffer belonging to the 74FCT807T series. It provides a 1:10 fan-out ratio, converting a single TTL-compatible input into ten TTL-compatible outputs. The device operates within a supply voltage range of 4.75V to 5.25V and supports maximum frequencies up to 100 MHz. It is housed in a 20-pin SOIC package with surface-mount installation. The component is designed for high-speed clock distribution applications requiring true TTL compatibility and low leakage currents.

Feature Summary

• Single 1:10 Clock Driver with TTL-compatible inputs and outputs
• Maximum operating frequency of 100 MHz
• Supply voltage range of 4.75V to 5.25V
• Housed in a 20-lead Small Outline Integrated Circuit (SOIC) package

Applications

• High-speed clock distribution networks
• Bus-oriented system timing circuits
• Digital logic interface buffering

Procurement Notes

The 74FCT807CTSOG is listed as an obsolete or end-of-life product by the manufacturer. Availability is restricted to existing stock from authorized distributors or secondary markets. Verification of authenticity and storage history is critical due to the component's discontinued status. Buyers should confirm the specific suffix 'SOG' corresponds to the SOIC-20 package variant when sourcing replacements.

Selection Notes

Select this component for designs requiring a single-input, ten-output TTL clock buffer at speeds up to 100 MHz. Ensure the system power supply strictly adheres to the 4.75V–5.25V range. For modern designs, consider that this part is obsolete; verify if newer FCT family members or alternative manufacturers offer equivalent pinouts and electrical characteristics for new hardware development.

Part Context

This part belongs to the 74FCT (Fast CMOS TTL) family, which bridges the speed of CMOS technology with the drive strength and input/output compatibility of TTL logic. The 74FCT807T series specifically focuses on clock distribution. The 'C' suffix typically denotes commercial temperature range operation (0°C to 70°C), while 'SOG' specifies the 20-lead SOIC package type.

Replacement Considerations

Direct pin-to-pin replacements may include other 74FCT807 variants with different packages (e.g., SSOP or QSOP) or updated manufacturing sources. Verify that any substitute maintains the 1:10 fan-out, 100 MHz frequency capability, and 5V TTL I/O levels. Check for RoHS compliance updates if environmental regulations apply.
