74FCT20807PYGI8

Overview

The 74FCT20807PYGI8 is a clock fan-out buffer manufactured by Renesas Electronics Corporation, belonging to the 74FCT logic series. It provides a 1:10 input-to-output ratio for clock distribution applications. The device operates with an LVTTL input and LV TTL outputs, supporting a maximum frequency of 166 MHz. It functions within a supply voltage range of 2.3V to 2.7V and is housed in a 20-SSOP package (0.154 inch / 3.90mm width). The component is rated for industrial temperatures from -40°C to +85°C.

Feature Summary

• 1:10 Clock Fan-Out Buffer
• Maximum Frequency: 166 MHz
• Supply Voltage: 2.3V ~ 2.7V
• Package: 20-SSOP

Applications

• Clock distribution networks
• High-speed digital systems requiring low skew buffering
• Embedded processing clock generation

Procurement Notes

Verify component status as the related 74FCT20807QGI variant is listed as obsolete. Confirm RoHS compliance and MSL level 1 availability through authorized distributors. Check for specific EOL notifications or PCN updates regarding the PYGI8 suffix designation before procurement planning.

Selection Notes

Select this component when a 3.3V-compatible 1:10 clock buffer is required with a lower 2.5V nominal supply voltage. Ensure the design accommodates the 2.3V to 2.7V operating range. Compare against the 74FCT3807 series if a 3.3V supply (3V-3.6V) is preferred instead of the 2.5V range specified here.

Part Context

This part is part of the broader 74FCT family of high-speed CMOS logic devices originally developed by IDT and now managed by Renesas. It serves as a specialized clock driver within the company's portfolio of timing and synchronization solutions, distinct from general-purpose logic gates.
