49FCT3805APYGI

Overview

The Renesas 49FCT3805APYGI is a dual 1-to-5 clock driver and buffer belonging to the 49FCT series. It operates on a single 3V to 3.6V supply voltage and features LVCMOS/LVTTL input and output types. The device is housed in a 20-SSOP package with a width of 5.30mm. Designed for high-speed clock distribution, it provides low capacitance inputs to maintain signal integrity. The component supports an operating temperature range from -40°C to +85°C and includes independent output enable controls for each driver bank.

Feature Summary

• Dual 1:5 fanout clock driver architecture
• LVCMOS/LVTTL compatible I/O levels
• Low capacitance inputs for high-speed performance
• Independent output enable control per bank

Applications

• High-speed clock distribution networks
• Address bus distribution systems
• Point-to-point transmission line driving
• PLL driving applications requiring diagnostics

Procurement Notes

Verify the specific suffix against the datasheet to confirm package type and temperature grade. The 'PYG' designation typically corresponds to the SSOP-20 package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply chain sources provide valid traceability for automotive or industrial qualification requirements.

Selection Notes

Select this component when dual independent clock buffers with 1:5 fanout are required within a 3.3V logic environment. The SSOP-20 package is suitable for surface-mount assembly where space constraints allow for its 5.30mm width. Verify that the input signal characteristics match the LVCMOS/LVTTL specifications to ensure proper logic level compatibility across the operating temperature range.

Part Context

This part belongs to the 49FCT family of fast CMOS clock drivers. It shares functional similarities with other variants such as the 49FCT3805ASOGI8, which utilizes a SOIC-20 package instead of SSOP. The device is manufactured by Renesas Electronics Corporation, formerly IDT, and serves as a specialized solution for skew-critical clock distribution tasks.

Replacement Considerations

Publicly confirmed substitute part numbers include PI49FCT32805QE from Diodes Incorporated. Verify pinout compatibility and electrical parameter alignment before substitution. Other family members like the 49FCT3805ASOGI8 offer identical functionality but differ in physical packaging.
