74FCT3807EPYGI

Overview

The Renesas Electronics Corporation 74FCT3807EPYGI is a single-input, ten-output clock buffer and driver within the 74FCT series. It operates with an LVTTL input and provides CMOS/TTL outputs. The device supports a maximum frequency of 166 MHz and functions on a supply voltage range of 3V to 3.6V. It is housed in a 20-SSOP package (5.30mm width) designed for surface mount installation. The component is rated for operation between -40°C and 85°C. This specific part number is currently listed as obsolete by the manufacturer.

Feature Summary

• Single-to-ten fan-out buffering capability
• Maximum operating frequency of 166 MHz
• LVTTL input interface with CMOS/TTL output compatibility
• Operates on 3V to 3.6V power supply

Applications

• Clock distribution networks requiring high-speed signal splitting
• System timing architectures utilizing LVTTL sources
• Industrial equipment operating within extended temperature ranges

Procurement Notes

This component is officially discontinued and no longer in active production. Verification of availability is restricted to existing stock held by distributors or secondary market suppliers. Designers should prioritize alternative components for new hardware development due to the lack of future manufacturing support.

Selection Notes

Engineers selecting this part must account for its obsolete status. The primary technical differentiator is the 166 MHz speed rating compared to the standard 100 MHz variants in the same family. Ensure the design environment accommodates the 20-SSOP footprint and that the system logic levels align with the specified LVTTL input requirements.

Part Context

The 74FCT3807EPYGI belongs to the broader 74FCT3807 product family, which includes various packaging options such as SOIC, QSOP, and TSSOP. The 'E' suffix typically denotes the extended industrial temperature range (-40°C to 85°C), distinguishing it from commercial grade versions. The 'PYGI' suffix specifies the SSOP package type and RoHS compliance.

Replacement Considerations

Publicly confirmed substitute part numbers include the 74FCT3807APYGI8 and the 74FCT3807AQG8. These alternatives offer similar 1:10 buffering functionality but may differ in package dimensions or specific electrical characteristics. Verify pinout compatibility before substitution.
