74AHCT240BQ,115

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT240BQ,115 is an octal buffer and line driver featuring inverting logic with three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device contains two independent four-bit buffers controlled by separate active-low output enable inputs (1OE and 2OE). It utilizes a 20-terminal DHVQFN package measuring 4.5 mm by 2.5 mm.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Inputs accept voltages exceeding the supply voltage for mixed-voltage translation
• All inputs feature Schmitt-trigger action for noise immunity
• Outputs provide balanced propagation delays
• ESD protection exceeds 2000 V under Human Body Model testing

Buffers, Drivers, Receivers, Transceivers Applications

• Translating signals between mixed voltage environments
• Driving high-capacitance or transmission-line loads
• Providing bus-oriented memory and clock buffering

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix BQ corresponds to the DHVQFN20 package variant. Confirm the temperature grade matches the required operational range of -40 °C to +125 °C. Ensure input voltage tolerances align with the target system's signal levels. Cross-reference the manufacturer part number against official Nexperia documentation to validate authenticity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an inverting octal buffer with three-state capability is required. It is suitable for applications needing TTL-compatible input levels at 5 V operation. Consider the DHVQFN package dimensions for PCB layout constraints. Verify that the overvoltage tolerant inputs meet the interface requirements of the driving circuitry.
