74FCT38074SDCGI8

Overview

The 74FCT38074SDCGI8 is a low skew, single input to four output LVCMOS clock buffer manufactured by Renesas Electronics. It belongs to the 74FCT series and is designed for high-performance clock distribution applications. The device features an additive phase jitter of sub 50fs, ensuring precise timing integrity. It operates with a supply voltage range of 3V to 3.6V and supports LVTTL inputs with CMOS/TTL outputs. The component is housed in a 16-SSOP package and is rated for operation within the commercial temperature range of 0°C to 70°C.

Feature Summary

• Single input to four output LVCMOS clock buffer configuration
• Additive phase jitter performance of sub 50fs
• Low skew design for accurate clock distribution
• Compatible with LVTTL inputs and CMOS/TTL outputs

Applications

• High-speed digital system clock distribution
• Data communication equipment requiring low jitter
• Computer peripheral interfaces
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'GI8' against the manufacturer's official datasheet to confirm packaging details, such as reel specifications or tape-and-reel quantities. Ensure that the ordering information matches the exact part number variant required for the intended application, as suffixes often denote package type or environmental compliance status.

Selection Notes

Select this component when a low-skew, four-output clock buffer is required for LVCMOS systems. The sub 50fs additive jitter makes it suitable for sensitive timing applications. Compare the 1:4 fan-out ratio against other variants like the 74FCT3807 (1:10) if higher fan-out is needed. Confirm that the 16-SSOP package fits the PCB layout constraints.

Part Context

This part is part of the broader 74FCT family of fast CMOS logic devices. It shares functional similarities with other clock buffers in the series but is distinct due to its 1:4 output configuration and specific jitter characteristics. It serves as a solution for distributing a single clock signal to multiple synchronous components with minimal distortion.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative 1:4 LVCMOS clock buffers from the same manufacturer or other vendors, ensuring compatibility with the 3V-3.6V supply voltage and SSOP package footprint.
