49FCT805PYGI

Overview

The Renesas Electronics Corporation 49FCT805PYGI is a dual clock driver and distribution buffer belonging to the 49FCT series. It features two independent driver sections, each providing a 1:5 fanout ratio with CMOS outputs. The device operates on a single 5V supply voltage (4.5V to 5.5V) and supports input signals compatible with LVCMOS or LVTTL standards. Packaged in a 20-lead SSOP format, it is designed for high-speed clock distribution applications requiring low skew and signal integrity.

Feature Summary

• Dual independent clock driver sections with 1:5 fanout per section
• CMOS output drivers compatible with standard logic families
• LVCMOS/LVTTL input compatibility for flexible interfacing
• Operates within a 4.5V to 5.5V power supply range

Applications

• High-speed clock distribution networks
• Address bus buffering in computer systems
• Data bus driving for multiple receivers
• Point-to-point transmission line driving

Procurement Notes

Verify component status as this part may be discontinued or subject to end-of-life notifications. Confirm package dimensions and pinout compatibility during integration. Check RoHS compliance documentation for environmental regulations. Ensure supply chain stability due to potential obsolescence risks associated with legacy FCT series components.

Selection Notes

Select this component when a dual 1:5 clock buffer with CMOS outputs is required. Verify that the system operates at 5V logic levels. Consider thermal performance and PCB layout for high-frequency signals. Compare against newer FCT family members if long-term availability is critical for the design lifecycle.

Part Context

This component is part of the broader 49FCT805 family, which includes variants with different packages such as SOIC and QSOP, and output types like TTL. The PYGI suffix specifically denotes the SSOP-20 package variant manufactured by Renesas Electronics, formerly IDT.

Replacement Considerations

Direct substitutes include other 49FCT805 variants with identical electrical characteristics but different packaging, such as 49FCT805CTSOG or 49FCT805CTQG. Cross-reference with newer Renesas clock drivers if the 49FCT series is obsolete.
