74FCT807CTPYGI8

Overview

The 74FCT807CTPYGI8 is a clock buffer and distribution integrated circuit manufactured by Renesas Electronics Corporation. It functions as a 1:10 fan-out buffer with TTL outputs, designed for high-speed clock signal distribution. The device operates within a supply voltage range of 4.75V to 5.25V and supports maximum frequencies up to 100 MHz. It features LVTTL input compatibility and CMOS/TTL output drive capabilities. The component is housed in a 20-SSOP package with a width of 5.30mm and is rated for operation across an industrial temperature range of -40°C to +85°C.

Feature Summary

• 1:10 Clock Fan-Out Buffer with TTL Outputs
• Operating Supply Voltage: 4.75V to 5.25V
• Maximum Frequency: 100 MHz
• Package: 20-SSOP (0.209 inch / 5.30mm width)

Applications

• Clock distribution networks requiring TTL-compatible outputs
• High-speed digital systems utilizing 5V logic families
• Bus-oriented applications needing clock signal buffering

Procurement Notes

The 74FCT807CTPYGI8 is listed as an obsolete or end-of-life product by the manufacturer. Availability is limited to existing stock from distributors. Verification of RoHS compliance and specific manufacturing lot dates is recommended due to the component's discontinued status. Buyers should confirm lead times and authenticity through authorized channels given the EOL classification.

Selection Notes

Select this component when a 5V-powered 1:10 clock distribution solution with TTL outputs is required. Ensure the system operates within the 4.75V to 5.25V supply range. For designs requiring lower power consumption or different voltage levels, consider the 74FCT3807 series variants which support 3.3V operation. Verify that the 20-SSOP footprint matches the PCB layout constraints.

Part Context

This part belongs to the 74FCT family of Fast CMOS TTL-compatible logic devices. It shares functional similarities with the 74FCT807BTPYGI8 but differs in packaging and potentially speed grade. The 'CT' suffix typically denotes a specific speed bin or package variant within the 74FCT807T series. It serves as a legacy alternative to newer low-voltage clock drivers.

Replacement Considerations

Publicly confirmed substitute part numbers include IDT74FCT807CTQG8 and 74FCT3807APYGI8. The 74FCT3807 series offers similar functionality but operates at 3.3V, requiring level shifting if used in 5V systems. Direct pin-to-pin replacements in the same voltage domain may be limited due to the EOL status.
