54FCT245CTDB

Overview

The 54FCT245CTDB is an octal bidirectional bus transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a 20-pin CDIP package. The device supports a minimum operating temperature of -55°C and a maximum of +125°C. It features three-state outputs and functions as a non-inverting transceiver with one element containing eight bits per element.

Feature Summary

• Octal bidirectional data transfer capability
• Three-state output configuration
• Wide industrial temperature range support

Applications

• High-speed data bus systems
• Industrial control environments
• Military-grade electronic equipment

Procurement Notes

Verify the specific suffix CTDB confirms the 20-CDIP plastic dual in-line package and commercial/industrial grade specifications. Confirm RoHS compliance status, as military variants often differ from standard commercial offerings. Ensure the source document explicitly lists this part number to avoid confusion with similar FCT series components.

Selection Notes

Select this component for applications requiring robust bidirectional data transmission in harsh thermal conditions. The wide temperature range makes it suitable for demanding environments where standard commercial parts may fail. Verify that the 20-CDIP footprint matches the target PCB design constraints before finalizing the selection.

Part Context

This component belongs to the 54FCT logic family, designed for high-speed CMOS applications. It serves as a critical interface for moving data between buses in complex digital systems. The military-grade temperature rating distinguishes it from lower-cost commercial alternatives, ensuring reliability in extreme operational scenarios.

Replacement Considerations

The 74FCT245ATSOG is a related bidirectional transceiver but differs in package type (SOIC vs. CDIP) and operating temperature range (-40°C to +85°C). Substitution requires verifying mechanical fit and thermal requirements.
