49FCT806PYG8

Overview

The 49FCT806PYG8 is a dual 1:5 inverting clock driver manufactured by Renesas Electronics. It utilizes advanced CMOS technology to provide high-speed clock distribution with low skew and signal integrity. The device features two independent driver banks, each capable of driving five outputs from a single input. It operates within a supply voltage range of 4.5V to 5.5V and supports CMOS and LVTTL input/output logic levels. Designed for applications requiring precise timing, it includes output enable controls for each bank. The component is housed in a 20-SSOP package with a width of 5.30mm and is rated for operation between 0°C and 70°C.

Feature Summary

• Dual 1:5 inverting clock driver architecture
• CMOS and LVTTL compatible I/O levels
• Supply voltage range of 4.5V to 5.5V
• Independent output enable control per bank

Applications

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

Procurement Notes

Verify the current lifecycle status as the related 49FCT806SOG8 variant is marked as End-of-Life (EOL). Confirm availability through authorized distributors, noting that stock may be limited or restricted in certain regions. Ensure compliance with RoHS directives and check for any Product Change Notifications (PCN) affecting manufacturing sources or packaging before procurement.

Selection Notes

Select this component when dual-channel 1:5 fanout with inversion is required for CMOS/LVTTL interfaces. Ensure the system power supply remains stable within the 4.5V–5.5V range. Verify that the 20-SSOP package dimensions fit the PCB layout constraints. Consider the operating temperature range of 0°C to 70°C against environmental requirements.

Part Context

This part belongs to the 49FCT series of clock drivers and buffers. It shares functional similarities with other FCT family members but is distinct in its dual 1:5 inverting configuration. Related variants include the non-inverting 49FCT805 and different package options like SOIC or QSOP. The 'PYG8' suffix indicates the specific SSOP package and tape-and-reel shipping format.

Replacement Considerations

Direct pin-compatible substitutes within the same series include the 49FCT805CTPYG8 (non-inverting) or other 49FCT806 variants with different packages such as 49FCT806SOG8. Verify logical inversion requirements and package footprint compatibility before substitution.
