74FCT3807EPYGI8

Overview

The 74FCT3807EPYGI8 is a single clock fan-out buffer manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3V to 3.6V and supports a maximum frequency of 166 MHz. The device accepts LVTTL input signals and provides CMOS/TTL outputs in a 1:10 ratio. It is housed in a 20-SSOP package with a width of 5.30mm (0.209 inches). The component is rated for an operating temperature range of 0°C to 70°C and is currently designated as obsolete.

Feature Summary

• Single circuit configuration with 1:10 input-to-output ratio
• Maximum operating frequency of 166 MHz
• LVTTL input interface compatible with CMOS/TTL output levels
• Surface-mount installation in a 20-SSOP package

Applications

• Clock distribution networks requiring signal buffering
• System timing architectures utilizing TTL-compatible logic families
• Industrial control systems operating within commercial temperature ranges

Procurement Notes

This component has reached end-of-life status, with discontinuation notifications dated May 30, 2025. Verification of remaining stock availability from authorized distributors is required before procurement planning. Designers should initiate replacement strategies immediately due to the obsolescence status.

Selection Notes

Select this part only if legacy compatibility with LVTTL inputs and 166 MHz performance at 3.3V is strictly required. Verify that the 0°C to 70°C commercial temperature range meets system environmental specifications. Ensure the 20-SSOP footprint matches the existing PCB layout constraints.

Part Context

The 74FCT3807EPYGI8 belongs to the 74FCT3807D series within the broader 74FCT family. It serves as a high-speed clock driver designed for distributing reference clocks across multiple loads. The 'E' suffix typically denotes the commercial temperature grade, while 'PYGI8' specifies the SSOP package and tape-and-reel packaging format.
