74FCT38075DCGI

Overview

The 74FCT38075DCGI is a single-channel fan-out clock buffer manufactured by Renesas Electronics Corporation. It provides one input to five outputs with a maximum operating frequency of 166 MHz. The device accepts LVTTL logic levels and drives CMOS or TTL loads. It operates within a supply voltage range of 3V to 3.6V and functions across an industrial temperature range of -40°C to +85°C. The component is housed in an 8-SOIC package (0.154 inch width) and is surface-mountable. It complies with RoHS3 standards and has a Moisture Sensitivity Level of 1.

Feature Summary

• Single circuit configuration providing 1:5 fan-out ratio
• Maximum output frequency of 166 MHz
• LVTTL input compatible with CMOS/TTL output drivers
• Industrial temperature range from -40°C to +85°C

Applications

• Clock distribution networks requiring signal buffering
• System timing architectures utilizing LVTTL sources
• High-speed digital circuits needing low-skew clock propagation

Procurement Notes

Verify the current production status, as availability may vary. Confirm that the 8-SOIC package dimensions match the target PCB footprint. Ensure the design supports the specified 3V to 3.6V supply voltage range. Check for RoHS3 compliance requirements if exporting to regulated regions. Validate that the LVTTL input thresholds are compatible with the driving source.

Selection Notes

Select this component when a single LVTTL clock source must drive up to five CMOS or TTL loads at frequencies up to 166 MHz. The 8-SOIC package is suitable for space-constrained surface-mount designs. Consider the -40°C to +85°C operating range for industrial applications. Verify that the power supply voltage remains within the 3V to 3.6V window for optimal performance.

Part Context

This part belongs to the 74FCT series of high-speed CMOS logic devices. The 74FCT38075 family specifically focuses on clock buffering and distribution. The 'DCGI' suffix indicates the specific package type (8-SOIC), temperature grade (industrial), and tape/reel or tube packaging variant depending on the specific distributor listing. It serves as a buffer to isolate the source clock from load capacitance.

Replacement Considerations

The CDCVF2505D from Texas Instruments is listed as a similar alternative. Verify pinout compatibility and electrical specifications before substitution.
