74AHC244BQ,115

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC244BQ,115 is an octal buffer and line driver featuring three-state outputs, housed in a DHVQFN20 package (SOT764-1). It operates within a supply voltage range of 2.0 V to 5.5 V. The device provides balanced propagation delays with Schmitt-trigger inputs for high noise immunity. Static characteristics include a maximum input leakage current of 2.0 μA at -40 °C to +125 °C and a maximum supply current of 80 μA under specified conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features two independent output enable controls (1OE and 2OE) for managing three-state outputs.
• Includes overvoltage tolerant inputs allowing operation in mixed voltage environments up to 5.5 V.
• Provides ESD protection exceeding 2000 V via Human Body Model and 1000 V via Charge Device Model.

Buffers, Drivers, Receivers, Transceivers Applications

• Mixed voltage translation between different logic families
• Memory address drivers
• Clock distribution buffers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the DHVQFN20 package configuration. Ensure that the required temperature range aligns with the component's specified operating limits. Confirm RoHS compliance status through the latest product data sheet before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an 8-bit non-inverting buffer with three-state capability is required in a compact leadless package. The wide supply voltage range supports various digital logic levels. Verify that the thermal dissipation requirements are met by the PCB layout, as power derating applies above specific ambient temperatures.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC logic family, designed for high-speed CMOS applications. It serves as a standard octal buffer solution within Nexperia's portfolio of logic ICs. The BQ suffix specifically denotes the DHVQFN20 package variant, distinguishing it from SO or TSSOP versions.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHCT244BQ,115 is a compatible alternative within the same package offering TTL-compatible input levels instead of CMOS levels. Other variants such as the 74AHC244D or 74AHC244PW provide identical functionality but utilize different physical packages.
