74FCT3807AQGI8

Overview

The 74FCT3807AQGI8 is a low skew, single-input to ten-output LVCMOS clock buffer manufactured by Renesas Electronics. It operates within a supply voltage range of 1.8V to 3.3V and supports maximum frequencies up to 166 MHz. The device features sub-50fs additive phase jitter performance. It is housed in a 20-pin QSOP package with dimensions of 8.7 x 3.8 x 1.47 mm and a lead pitch of 0.64 mm. The component is designed for surface mount installation and functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Low skew architecture with sub-50fs additive phase jitter
• 1:10 fan-out ratio from single LVCMOS input to ten CMOS/TTL outputs
• Wide supply voltage operation from 1.8V to 3.3V
• High-speed performance supporting frequencies up to 166 MHz

Applications

• Clock distribution networks requiring low jitter
• High-speed data acquisition systems
• Telecommunications equipment clocking
• Industrial control system timing

Procurement Notes

Verify the specific suffix 'AQGI8' against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the 20-QSOP form factor. Check for any recent Product Change Notifications (PCNs) regarding assembly location or material composition changes before finalizing procurement plans.

Selection Notes

Select this component when sub-50fs jitter performance is critical for signal integrity. Confirm that the 1.8V to 3.3V operating range matches the target system power rails. Verify that the 166 MHz maximum frequency exceeds the required clock speed. Ensure the design accommodates the 20-pin QSOP physical dimensions and thermal requirements.

Part Context

This part belongs to the 74FCT series of high-speed CMOS logic devices. It serves as a specialized clock buffer variant within the broader 74FCT3807 family, distinguished by its specific packaging and extended temperature capabilities compared to standard commercial variants.

Replacement Considerations

Direct substitutes include other 74FCT3807 variants with matching 20-QSOP packages and industrial temperature ratings. Cross-reference pinouts and electrical specifications carefully, as suffixes may indicate differences in packaging or compliance standards rather than functional changes.
