74FCT38072SDCGI

Overview

The 74FCT38072SDCGI is a low skew, single-input to two-output clock buffer manufactured by Renesas Electronics. It operates within a supply voltage range of 1.8V to 3.3V and supports input/output clock frequencies up to 200MHz. The device features extremely low output skew of 50ps and additive phase jitter of 50fs RMS. Packaged in an 8-pin SOIC (4.9 x 3.9 x 1.5 mm) with a 1.27mm pitch, it functions across an extended temperature range of -40°C to +85°C. This component utilizes low-power CMOS technology for efficient clock distribution.

Feature Summary

• Low skew outputs with 50ps specification
• Additive phase jitter of 50fs RMS
• Input/Output clock frequency up to 200MHz
• Operating voltages from 1.8V to 3.3V

Applications

• Clock distribution networks requiring low jitter
• High-speed digital systems with LVCMOS/LVTTL interfaces
• Portable electronics utilizing low-voltage operation

Procurement Notes

Verify the specific suffix 'SDCGI' against official Renesas documentation to confirm package dimensions and lead finish specifications. Ensure compatibility with existing PCB footprints for the 8-SOIC form factor. Confirm RoHS compliance status through current datasheets as manufacturing processes may evolve.

Selection Notes

Select this component when sub-50fs jitter and 50ps skew are critical for signal integrity. It serves as a direct replacement for legacy IDT variants in the 74FCT38072 family. Verify that the 1:2 fan-out ratio meets system requirements compared to other series members like the 74FCT38075.

Part Context

This part belongs to the 74FCT38072S series, which represents an evolution of the classic 74FCT logic family optimized for high-frequency performance. It replaces older IDT-branded parts such as the IDT74FCT38072DCI, maintaining pin compatibility while offering improved electrical characteristics and lower power consumption.

Replacement Considerations

The IDT74FCT38072DCI is listed as obsolete. The 74FCT38072DCGI8 is identified as a parameter-equivalent alternative available from Renesas.
