74AHC240BQ,115

Buffers, Drivers, Receivers, Transceivers Overview

The 74AHC240BQ,115 is an octal buffer and line driver manufactured by NXP Semiconductors. It features inverting logic with three-state outputs housed in a DHVQFN20 package (SOT764-1). The device operates within a supply voltage range of 2.0 V to 5.5 V. Propagation delay typically ranges from 2.8 ns to 7.5 ns depending on load conditions. It includes two output enable inputs controlling four outputs each.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Balanced propagation delays for consistent signal timing
• All inputs feature Schmitt-trigger action for noise immunity
• Inputs are overvoltage tolerant, allowing use as translators in mixed-voltage environments

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmissions

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '115' corresponds to the DHVQFN20 tape and reel packaging configuration. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the thermal pad connection aligns with your PCB layout guidelines for optimal heat dissipation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal inverting buffer with high-speed performance is required. The AHC series offers CMOS input levels suitable for modern digital systems. Consider the DHVQFN20 package if space constraints necessitate a compact surface-mount solution with enhanced thermal properties.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC family of high-speed CMOS logic devices. It serves as an octal buffer/line driver variant within the broader 74xx series ecosystem. The BQ suffix indicates the specific DHVQFN20 package type used for surface mounting.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHCT240BQ,115 is a compatible alternative offering TTL input levels instead of CMOS levels while maintaining the same pinout and functionality.
