74FCT3807AQGI

Overview

The Renesas Electronics Corporation 74FCT3807AQGI is a single clock buffer and driver within the 74FCT series. It provides a 1:10 fan-out ratio, accepting one LVTTL input to drive ten CMOS or TTL outputs. The device operates on a supply voltage ranging from 3 V to 3.6 V and supports maximum output frequencies up to 166 MHz. Packaged in a 20-pin QSOP (SSOP) with a width of 3.90 mm, it functions across an industrial temperature range of -40°C to +85°C. Key electrical characteristics include a typical operating supply current of 15.5 mA.

Feature Summary

• 1:10 Clock Fan-Out Distribution
• LVTTL Input with CMOS/TTL Outputs
• 166 MHz Maximum Operating Frequency
• Industrial Temperature Range (-40°C to +85°C)

Applications

• Clock distribution networks in high-speed digital systems
• Buffering clock signals for multiple synchronous components
• System timing architecture in telecommunications equipment

Procurement Notes

Verify the specific package variant, as datasheets may list both SSOP and QSOP designations for this part number. Confirm RoHS compliance status and check for any Product Change Notices regarding assembly location or labeling updates prior to procurement.

Selection Notes

Select this component when a single low-voltage TTL clock source must drive ten standard CMOS or TTL loads. Ensure the system power supply remains strictly between 3 V and 3.6 V. Verify that the required operating frequency does not exceed 166 MHz and that the thermal environment stays within the specified -40°C to +85°C range.

Part Context

This component belongs to the 74FCT family of high-speed CMOS logic devices. It serves as a dedicated clock driver designed to maintain signal integrity while providing significant fan-out capability. The part is often referenced by its legacy IDT designation, IDT74FCT3807AQGI.

Replacement Considerations

The 74FCT3807AQG is listed as a parameter-equivalent alternative. Other variants such as the 74FCT3807APYG offer similar functionality but differ in packaging and temperature specifications.
