74FCT3807PYGI8

Overview

The 74FCT3807PYGI8 is a single clock fan-out buffer manufactured by Renesas Electronics. It provides a 1:10 input-to-output ratio, distributing one LV TTL input signal to ten CMOS/TTL outputs. The device supports maximum frequencies of 100 MHz and operates within a supply voltage range of 3V to 3.6V. It is housed in a 20-SSOP package with a width of 5.30mm. The component functions as a clock driver suitable for high-speed digital systems requiring precise timing distribution.

Feature Summary

• Single circuit configuration with 1:10 fan-out ratio
• Maximum operating frequency of 100 MHz
• LVTTL input interface driving CMOS and TTL outputs
• Operates on a 3V to 3.6V power supply

Applications

• Clock distribution networks in high-speed digital circuits
• System timing synchronization in communication equipment
• Buffering reference clocks for multiple synchronous components

Procurement Notes

Verify the specific suffix PYGI8 against the manufacturer's current datasheet IDT74FCT3807/A to confirm pinout and electrical characteristics. Check Product Change Notices (PCN) regarding assembly source updates or label changes issued in September 2018 and December 2022. Confirm availability status as the part may be subject to discontinuation notices effective May 2025.

Selection Notes

Select this component when a 1:10 split is required for LV TTL sources. Ensure the load capacitance and trace lengths are compatible with the 100 MHz maximum frequency specification. Compare against the 74FCT3807S series if lower skew performance below 50fs is necessary, as the standard 74FCT3807 variants do not explicitly list sub-50fs jitter metrics in general descriptions.

Part Context

This part belongs to the 74FCT family of high-speed CMOS logic devices originally developed by Integrated Device Technology (IDT) and now produced by Renesas. The base model 74FCT3807 defines the core functionality, while the suffix PYGI8 indicates the specific tape-and-reel packaging and temperature grade options defined by the manufacturer's ordering nomenclature.

Replacement Considerations

The 5PB1106PGGI8 is listed as a substitute part number by the distributor. Verify functional equivalence and pin compatibility before replacement.
