74FCT3807AQG

Overview

The Renesas Electronics Corporation 74FCT3807AQG is a single-channel clock fan-out buffer designed for high-speed digital systems. It accepts one LVTTL input and provides ten CMOS/TTL outputs, achieving a 1:10 distribution ratio. The device operates within a supply voltage range of 3V to 3.6V and supports maximum frequencies up to 100 MHz or 166 MHz depending on specific load conditions. Housed in a 20-lead SSOP package with a width of 3.90mm, it functions within an industrial temperature range of 0°C to 70°C and draws a typical operating current of 15.5 mA.

Feature Summary

• Single-input to ten-output clock distribution architecture
• LVTTL input compatibility with CMOS and TTL output levels
• Operational frequency support up to 166 MHz
• Surface-mount 20-SSOP (QSOP) packaging

Applications

• Clock signal distribution in high-speed data acquisition systems
• Fan-out buffering for microprocessor clock networks
• Timing synchronization in telecommunications equipment

Procurement Notes

Verify the specific suffix 'QG' against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match the design requirements. Confirm RoHS3 compliance status and check for any Product Change Notices (PCN) regarding labeling or assembly source changes that may affect long-term availability.

Selection Notes

Select this component when a single low-voltage TTL clock source requires driving multiple CMOS or TTL loads without signal degradation. Ensure the system power supply remains strictly between 3V and 3.6V. Verify that the 20-SSOP footprint fits the PCB layout constraints, noting the 3.90mm body width.

Part Context

This part belongs to the 74FCT series of fast CMOS logic devices manufactured by Renesas Electronics. It serves as a specialized clock driver variant within the broader 74FCT family, distinct from standard logic gates by its dedicated fan-out capability and optimized timing performance for clock tree applications.

Replacement Considerations

The 74FCT3807AQG is parameter-equivalent to the 74FCT3807AQG8. Designers should verify if the tape-and-reel packaging of the '8' suffix variant offers sufficient inventory for production volume compared to the cut-tape or tube options available for the base model.
