74LVC16244ADGG,112

Overview

The Nexperia 74LVC16244ADGG,11 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 provides 5 V tolerant inputs and outputs for interfacing with 5 V logic systems. The device includes IOFF circuitry to prevent backflow current during partial power-down states. Inputs utilize Schmitt-trigger action to tolerate slow rise and fall times. The component is housed in a TSSOP48 plastic thin shrink small outline package (SOT362-1) with 48 leads.

Feature Summary

• Features four independent output enables controlling groups of three-state outputs.
• Includes IOFF circuitry to disable outputs and prevent damaging backflow current when powered down.
• All data inputs incorporate bus hold circuits to maintain input states without external pull-up resistors.
• Provides high noise immunity through Schmitt-trigger action at all input terminals.

Applications

• Mixed 3.3 V and 5 V logic environments requiring level translation
• Partial power-down applications utilizing IOFF functionality
• Systems requiring tolerance for slow input signal transition rates

Procurement Notes

Verify the specific ordering suffix matches the required temperature range and package variant. Confirm that the DGG suffix corresponds to the TSSOP48 package type. Ensure compatibility with system voltage requirements between 1.2 V and 3.6 V. Check for any recent product change notices regarding assembly sites or labeling updates.

Selection Notes

Select this component for designs requiring 16-bit buffering with 5 V tolerance. The inclusion of bus hold on data inputs simplifies handling unused lines. Verify that the low inductance multiple power and ground pins meet the noise reduction requirements of the target application.

Part Context

This part belongs to the 74LVC16244A series manufactured by Nexperia. It is functionally related to the 74LVCH16244A, which shares similar characteristics but may differ in specific feature sets like bus hold availability. The ADGG designation specifically identifies the TSSOP48 package configuration within the broader family.

Replacement Considerations

The 74LVCH16244ADGG,11 serves as a direct functional substitute within the same package. Other variants such as the ADGV version offer an alternative TVSOP48 package option for space-constrained layouts.
