74HCT240FPVEL-E

Overview

The Renesas Electronics Corporation 74HCT240FPVEL-E is an octal buffer and line driver belonging to the HCT logic series. It features eight inverting outputs with three-state capability, allowing for controlled signal transmission on bus-oriented systems. The device operates within a supply voltage range of 4.5 V to 5.5 V and utilizes a 20-pin flat package (FP) configuration. Designed for CMOS technology, it provides high noise immunity and low power consumption suitable for general-purpose digital applications requiring signal buffering and inversion.

Feature Summary

• Octal configuration providing eight independent inverting channels for comprehensive bus management
• Three-state output control enabling multiple drivers to share common data lines without interference
• HCT logic compatibility ensuring direct interface with standard TTL-driven systems

Applications

• Bus-oriented memory addressing and data routing
• Clock distribution and signal buffering in digital circuits
• Inverting line drivers for communication interfaces

Procurement Notes

Verify the specific suffix VEL-E against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and lead-free material declarations directly from the manufacturer's current datasheet or product announcement. Ensure the component matches the required operating temperature range and voltage specifications for the target application environment before procurement.

Selection Notes

Select this component when an octal inverting buffer with three-state control is required for 5V CMOS logic systems. The HCT series ensures compatibility with existing TTL logic levels while offering improved noise margins. Consider the 20-pin flat package constraints for PCB layout and thermal dissipation requirements relative to similar devices in the 74HCT240 family.

Part Context

This part belongs to the widely used 74HCT240 family of octal buffers and line drivers. Renesas manufactures these components to meet industry-standard logic specifications, providing reliable signal conditioning for digital systems. The FP package variant offers a compact footprint suitable for surface-mount assembly processes in consumer and industrial electronics.

Replacement Considerations

Compatible substitutes include MM74HCT240MTC and CD74HCT240EX. Verify pinout compatibility and electrical parameters such as propagation delay and output drive strength before substitution.
