TC74HC240AF(EL,F)

Overview

The TC74HC240AF(EL,F) is an octal inverting buffer and line driver manufactured by Toshiba Semiconductor and Storage. It utilizes high-speed CMOS technology for robust logic performance. The device operates within a supply voltage range of 2.0 V to 6.0 V. It features eight independent input-output channels with inverted output polarity. The component is housed in a 20-pin SOP package suitable for surface mount applications.

Feature Summary

• Octal bus buffer architecture providing eight independent signal paths
• Inverting logic function for signal phase reversal
• High-speed CMOS fabrication for efficient operation

Applications

• Data bus buffering in digital systems
• Line driving for communication interfaces
• Signal inversion in logic circuits

Procurement Notes

Verify the specific ordering suffix (EL,F) to confirm the tape and reel packaging configuration required for automated assembly processes. Ensure compatibility with standard SOP-20 footprint dimensions during PCB layout design. Confirm RoHS compliance status through official documentation prior to final procurement decisions.

Selection Notes

Select this component when an octal inverting buffer is required for high-speed CMOS logic applications. Consider the 2V to 6V operating range for system power supply compatibility. Evaluate the SOP-20 package constraints against available board space and thermal requirements for the target environment.

Part Context

This part belongs to the TC74HC240A series of octal bus buffers. It shares functional similarities with the TC74HC241A non-inverting variant and the TC74HC244A tri-state version. All members utilize silicon gate C2MOS technology for consistent performance characteristics across the family.

Replacement Considerations

The TC74HC241AF(EL,F) serves as a direct substitute if non-inverting logic is acceptable. The TC74HC244AF(EL,F) provides tri-state control capabilities instead of continuous driving. Verify pinout compatibility before substituting these related components.
