74LVC16244ADL,118

Overview

The Nexperia 74LVC16244ADL 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 up to 5.5 V, enabling translation between mixed logic levels. The device includes four independent output enables (1OE through 4OE) controlling groups of four outputs each. Inputs utilize Schmitt-trigger action for noise immunity against slow signal transitions. The component is housed in a 48-lead SSOP package.

Feature Summary

• Provides 5 V tolerant input/output capabilities for interfacing with higher voltage logic systems
• Incorporates IOFF circuitry to prevent damaging backflow currents during partial power-down states
• Features Schmitt-trigger inputs to ensure tolerance for slower rise and fall times
• Utilizes low-inductance multiple power and ground pins to minimize electrical noise

Applications

• Translating signals between mixed 3.3 V and 5 V environments
• Partial power-down applications requiring isolation of powered-off buses
• High-noise environments utilizing Schmitt-trigger input buffering

Procurement Notes

Verify the specific package type upon ordering, as the datasheet revision history indicates that the SSOP48 variant was removed from the current product specification. Confirm availability of the TSSOP48 or TVSOP48 packages as direct replacements. Ensure compliance with RoHS standards and check for any recent longevity program updates regarding production status before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring 16-bit parallel data buffering with high-voltage interface compatibility. The inclusion of bus hold functionality on data inputs eliminates the need for external pull-up resistors for unused lines. Consider the device's low power consumption and high noise immunity for applications demanding reliable signal integrity across varying temperature ranges.

Part Context

This part belongs to the 74LVC/LVCH family of logic ICs manufactured by Nexperia. While the ADL suffix typically denotes an SSOP package, official documentation confirms this specific package version has been removed from the active product list. Current production focuses on the TSSOP48 and TVSOP48 variants within the same functional family.

Replacement Considerations

The 74LVC16244ADGG (TSSOP48) and 74LVCH16244ADGV (TVSOP48) are confirmed public substitutes offering identical logical functions. Verify pinout compatibility and package dimensions during integration.
