IDT49FCT805BTSO

Clock Buffers, Drivers Overview

The IDT49FCT805BTSO is a dual Fast CMOS buffer/clock driver manufactured by Renesas Electronics. It features two independent banks, each driving five outputs from a standard TTL-compatible input. The device provides extremely low output skew, pulse skew, and package skew for accurate clock distribution in high-speed systems. It includes a 'heart-beat' monitor output identical to other outputs for diagnostics and PLL driving. The component operates at a maximum frequency of 166 MHz with a 5V supply voltage.

Clock Buffers, Drivers Feature Summary

• Dual bank architecture with 1:5 fan-out per bank
• Guaranteed low skew (0.7 ns max commercial output skew)
• Integrated heart-beat monitor output
• 3-state outputs with active-low enable inputs

Clock Buffers, Drivers Applications

• High-speed system clock distribution
• Processor synchronization circuits
• PLL driving applications
• System diagnostics via heartbeat monitoring

Clock Buffers, Drivers Procurement Notes

Verify the manufacturing source as Integrated Device Technology or Renesas Electronics due to corporate acquisition history. Confirm RoHS compliance status, noting that non-green parts reached end-of-life on May 13, 2010. Ensure the specific ordering suffix matches the required package type and temperature range before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when low skew is critical for timing integrity in dual-bank clock distribution. Compare commercial (0°C to +70°C) and military (-55°C to +125°C) variants based on environmental requirements. Verify that the SOIC-20 package fits the board layout constraints and that the 5V logic levels match the system interface.

Clock Buffers, Drivers Part Context

This part belongs to the 49FCT series of Fast CMOS buffers and clock drivers. It was originally produced by Integrated Device Technology (IDT) before being acquired by Renesas Electronics. The device is designed to simplify clock distribution design by minimizing skew issues inherent in high-frequency digital systems.

Clock Buffers, Drivers Replacement Considerations

Check for equivalent parts within the 49FCT family such as the 49FCT806. Verify pin compatibility and electrical specifications against current available inventory from Renesas or authorized distributors.
