54FCT240ATDB

Overview

The 54FCT240ATDB is a dual four-bit buffer and line driver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 4.5V to 5.5V and features three-state outputs. The device provides an output high current of 12mA and an output low current of 48mA. It is housed in a 20-CDIP package with a pitch of 7.62mm. The component supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Dual four-bit buffer configuration with independent control
• Three-state output capability for bus-oriented applications
• High drive strength supporting 48mA low-level output current

Applications

• Bus-oriented memory and logic systems
• Clock drivers and buffer circuits
• High-performance register arrays

Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape/reel or tube packaging format, as variations exist within the FCT family. Confirm RoHS compliance status, as this specific part number indicates non-compliance with current environmental directives. Check for End-of-Life notices or Product Change Notifications regarding lead content or labeling updates before finalizing procurement plans.

Selection Notes

Select this component when a dual four-bit buffer with high drive capability is required for 5V CMOS logic systems. Ensure the application environment accommodates the specified wide industrial temperature range. Verify that the 20-pin CDIP through-hole package fits the target PCB layout constraints. Consider the three-state functionality for managing bidirectional data flow on shared buses.
