74ALVC244D,112

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ALVC244D,112 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 1.65 V to 3.6 V. The device provides two independent output enable inputs (1OE and 2OE), each controlling four outputs. Propagation delay ranges from 1.0 ns to 3.2 ns depending on voltage. Input transition rates are specified up to 20 ns/V at lower voltages. The component supports partial power-down via IOFF circuitry and includes Schmitt trigger action on all inputs.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features IOFF circuitry that disables outputs to prevent damaging backflow current during partial power-down applications.
• Includes Schmitt trigger action on all inputs to ensure tolerance for slow rise and fall times.
• Provides overvoltage tolerant inputs capable of interfacing with voltages up to 3.6 V.

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down mode operation
• Mixed voltage environments requiring level translation
• Bus interface applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Confirm RoHS compliance status and lifecycle stage prior to procurement. Ensure design-in compatibility with existing system voltage levels and signal integrity requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-speed buffering with low power consumption in the ALVC family. Consider the SO20 package dimensions and thermal characteristics for PCB layout. Verify input voltage thresholds match the driving logic levels across the full operating temperature range.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ALVC series of high-speed CMOS logic devices manufactured by Nexperia. It is functionally compatible with other octal buffers in the industry standard 74xx logic families but optimized for lower voltage operation and faster switching speeds compared to legacy HC or HCT variants.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check datasheets for alternative octal buffers such as the 74AHC244 or 74LVC244. Verify pinout compatibility and electrical specifications including propagation delay and drive current before substitution.
