74LVC16244AEV,118

Overview

The Nexperia 74LVC16244AEV,118 is a 16-bit buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V and supports inputs driven by either 3.3 V or 5 V devices, enabling translation in mixed-voltage environments. The device includes four independent output enable controls (1OE through 4OE) and Schmitt-trigger inputs for noise immunity. It incorporates IOFF circuitry to prevent backflow current during partial power-down states.

Feature Summary

• Provides 16-bit buffering with configurable grouping into four 4-bit, two 8-bit, or one 16-bit buffers
• Features five-volt tolerant inputs and outputs for direct interfacing with 5 V logic systems
• Includes IOFF circuitry to disable outputs and prevent damaging backflow currents when powered down
• Utilizes Schmitt-trigger action on all inputs to tolerate slower signal rise and fall times

Applications

• Mixed 3.3 V and 5 V logic level translation
• Partial power-down mode operation in portable electronics
• High-speed data bus buffering and line driving
• Systems requiring tolerance for slow input transition rates

Procurement Notes

Verify the specific package type against the ordering information table, as the datasheet revision history indicates that the AEV suffix was removed from production lists. Confirm current availability status directly with Nexperia or authorized distributors, as this part number may be superseded by other package variants such as ADGG or ADGV.

Selection Notes

Select this component for applications requiring wide supply voltage flexibility between 1.2 V and 3.6 V. Ensure the design accounts for the four separate output enable pins if independent control of data groups is required. Verify that the system's input signals meet the Schmitt-trigger thresholds to maximize noise immunity and timing reliability.

Part Context

This device belongs to the 74LVC16244A family of 16-bit buffers. The datasheet revision history explicitly notes that the 74LVC16244AEV type number was removed in version 15 (released February 2019). Current production typically utilizes alternative package options like the TSSOP48 or TVSOP48 formats.

Replacement Considerations

Public confirmed substitute part numbers include 74LVC16244ADGG,118 and 74LVC16244ADGV,118.
