Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'KATSO' against official IDT documentation to confirm package type and environmental compliance. Ensure the source document explicitly lists this part number as available from Integrated Device Technology or its authorized successors. Cross-reference the manufacturer details, as IDT assets are managed by Renesas Electronics. Confirm that the datasheet matches the exact electrical characteristics required for your design before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal data buffering with high-speed performance and three-state isolation. It is appropriate for applications needing strong drive currents on buses or clock lines. Consider the 20-pin SOIC package constraints and the 5V logic family compatibility. Verify that the dual enable feature aligns with your system's control logic requirements and that the operating temperature range meets your environmental specifications.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the FCT logic family, which utilizes FAST CMOS technology to provide high-speed performance comparable to TTL while maintaining CMOS power efficiency. The 74FCT541 series is widely used in digital systems for driving buses and managing data flow. IDT was a primary manufacturer of these logic devices before its acquisition by Renesas Electronics, which now manages the product line and associated documentation.
