74LVC16244ADGVJ

Overview

The Nexperia 74LVC16244ADGVJ is a 16-bit buffer and line driver featuring 3-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V and supports inputs driven by 3.3 V or 5 V devices, enabling translation in mixed-voltage environments. The device includes IOFF circuitry for partial power-down applications and Schmitt-trigger action on all inputs. It is housed in a TVSOP48 (SOT480-1) package with 48 leads.

Feature Summary

• Provides 5 V tolerant inputs and outputs for interfacing with 5 V logic systems
• Includes IOFF circuitry to disable outputs during partial power-down mode
• Features Schmitt-trigger action at all inputs to tolerate slower rise and fall times
• Offers high-impedance state when the supply voltage is zero

Applications

• Mixed 3.3 V and 5 V system environments
• Partial power-down applications requiring backflow current prevention
• Bus drivers and line drivers in digital circuits

Procurement Notes

Verify the specific ordering suffix 'J' against official Nexperia documentation to confirm packaging details such as reel specifications or tape-and-reel dimensions. Ensure the component matches the TVSOP48 package outline SOT480-1. Confirm that the temperature range and electrical characteristics align with the project requirements before finalizing procurement.

Selection Notes

Select this component when a 16-bit buffer with 3-state outputs is required for low-voltage applications between 1.2 V and 3.6 V. It is suitable for designs needing direct interface with TTL levels and protection against backflow currents during power-down states. Consider the TVSOP48 package constraints regarding body width and lead pitch for PCB layout.

Part Context

This part belongs to the 74LVC16244A series of 16-bit buffers and line drivers manufactured by Nexperia. It shares functional similarities with other LVC family members but is distinct in its 16-bit configuration and 5 V tolerance capabilities. The ADGVJ variant specifically denotes the TVSOP48 package type within this product line.

Replacement Considerations

The 74LVCH16244ADGV is a compatible alternative within the same family, offering bus hold functionality on data inputs which the standard LVC version lacks. Verify pin compatibility and electrical specifications before substitution.
