54FCT240CTDB

Overview

The 54FCT240CTDB is a CMOS logic buffer manufactured by Renesas Electronics Corporation, housed in a 20-CDIP through-hole package. It operates within a supply voltage range of 4.5V to 5.5V and features two independent elements, each providing four bits of buffering. The device delivers an output current of 12mA at high state and 48mA at low state. It supports tri-state outputs and functions across an operating temperature range of -55°C to 125°C.

Feature Summary

• Provides dual-channel buffering with four-bit capacity per channel for signal inversion and isolation.
• Features tri-state outputs to facilitate bus-oriented systems and controlled data flow.
• Designed for robust operation across extended industrial temperature ranges.

Applications

• Bus-oriented memory interface buffering
• Clock distribution networks requiring signal inversion
• Industrial control system I/O isolation

Procurement Notes

Verify component authenticity due to End-of-Life status. Confirm RoHS compliance requirements as the part does not meet RoHS standards. Validate package integrity for the 20-CDIP form factor. Check for specific manufacturer labeling changes documented in Product Change Notices. Ensure compatibility with existing board layouts before finalizing procurement decisions.

Selection Notes

Select this component when inverting buffers are required for 5V CMOS logic families. Consider the 20-CDIP package for through-hole assembly needs. Evaluate the 12mA/48mA drive strength against load requirements. Verify that the extended temperature range meets environmental specifications. Compare against non-inverting alternatives if signal polarity preservation is necessary.

Part Context

This part belongs to the FCT logic family, designed for high-speed CMOS applications. It serves as a successor or alternative to standard 74-series logic components. The device integrates buffering capabilities into a compact dual-element configuration. It is intended for use in digital systems requiring reliable signal transmission and inversion.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The component is listed as End-of-Life. Designers should consult official replacement guides or contact the manufacturer directly for qualified alternatives.
