74FCT38074DCGI8

Overview

The 74FCT38074DCGI8 is a clock fanout buffer manufactured by Renesas Electronics Corporation. It provides a 1:4 input-to-output ratio with a maximum frequency of 166 MHz. The device operates on a supply voltage range of 3V to 3.6V and supports LVTTL inputs with CMOS/TTL outputs. It is housed in an 8-SOIC package (0.154 inch width) and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Provides low skew clock distribution for high-speed digital systems
• Converts single LVTTL input signal into four buffered outputs
• Designed for 3.3V CMOS logic applications

Applications

• Clock distribution networks in high-performance computing systems
• Buffering clock signals for FPGA or ASIC synchronization
• Fanout buffering in telecommunications equipment

Procurement Notes

This component is officially marked as obsolete and is no longer manufactured by Renesas Electronics Corporation. Procurement should focus on identifying verified replacement parts from the manufacturer's recommended substitute list. Verify that any alternative components meet the required pinout, electrical specifications, and thermal performance before integration into existing designs.

Selection Notes

Select this component only if legacy compatibility with the 8-SOIC package and 166 MHz 1:4 fanout capability is strictly required. Due to its obsolete status, engineers must evaluate modern replacements that offer equivalent timing characteristics and voltage levels. Ensure the selected substitute maintains the same input/output logic families and physical footprint constraints.

Part Context

The 74FCT38074DCGI8 belongs to the 74FCT series of high-speed CMOS logic devices. This series is characterized by fast propagation delays and compatibility with standard TTL logic levels while operating at 3.3V. The specific model serves as a dedicated clock driver within this family, designed to maintain signal integrity across multiple branches.

Replacement Considerations

Verify official substitutes such as the IDT74FCT38074 series equivalents. Confirm that replacement packages match the 8-SOIC form factor and that electrical parameters like skew and drive strength are comparable.
