49FCT3805APYG8

Overview

The Renesas 49FCT3805APYG8 is a dual 1-to-5 clock driver and buffer designed for high-speed clock distribution. It operates within a supply voltage range of 3V to 3.6V, utilizing LVCMOS input and output logic levels. The device features two independent driver banks, each providing a 1:5 fanout with individual output enable controls. Packaged in a 20-pin SSOP (0.209 inch width) surface-mount format, it supports an industrial operating temperature range from -40°C to +85°C. The component draws a typical operating current of 20 mA and is RoHS compliant.

Feature Summary

• Dual 1:5 fanout clock distribution with independent output enables
• LVCMOS compatible inputs and outputs for signal integrity
• Industrial temperature range (-40°C to +85°C)
• Low capacitance inputs for high-speed performance

Applications

• High-speed clock distribution networks
• Address bus distribution requiring low skew
• Point-to-point transmission line driving
• PLL driving applications with heartbeat monitoring

Procurement Notes

Verify the package type matches the design requirements, as the 'A' suffix typically denotes SSOP while other variants may use SOIC. Confirm the specific suffix 'G8' against the manufacturer's latest datasheet to ensure correct tape-and-reel packaging specifications and RoHS compliance status before ordering.

Selection Notes

Select this component when dual independent 1:5 clock buffering is required with LVCMOS compatibility. Ensure the system power supply remains strictly between 3V and 3.6V. Verify that the 20-SSOP footprint fits the PCB layout constraints and that the -40°C to +85°C temperature rating meets the environmental conditions of the target application.

Part Context

This part belongs to the 49FCT series of fast CMOS clock drivers. It shares functional similarities with the 49FCT3805D-E but differs in packaging and commercial/industrial grade specifications. The 'A' prefix often indicates specific packaging or grade variations within the Renesas portfolio compared to standard IDT-branded equivalents.

Replacement Considerations

Publicly listed substitutes include Diodes Incorporated PI49FCT32805QE. Verify pinout compatibility and electrical parameters against the original datasheet before substitution.
