74LVC16244ADGG,118

Overview

The 74LVC16244ADGG,118 is a 16-bit buffer and line driver manufactured by Nexperia. It features three-state outputs controlled by four independent output enable inputs (1OE to 4OE). The device operates within a supply voltage range of 1.2 V to 3.6 V and supports input voltages up to 5.5 V. It utilizes Schmitt-trigger inputs for noise immunity and includes IOFF circuitry for partial power-down protection. The component is housed in a TSSOP48 package (SOT362-1) with a body width of 6.1 mm.

Feature Summary

• Provides 5 V tolerant inputs and outputs for interfacing with 5 V logic systems
• Includes IOFF circuitry to disable outputs and prevent backflow current during partial power-down
• Features Schmitt-trigger action on all data inputs to tolerate slower rise and fall times
• Utilizes low inductance multiple power and ground pins to minimize noise and ground bounce

Applications

• Translating signals between mixed 3.3 V and 5 V environments
• Driving high-capacitance or long transmission lines as a line driver
• Providing bus isolation in multibyte flow-through architectures

Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the temperature range specification aligns with the application environment requirements. Ensure compatibility with the target system's voltage levels and signal integrity needs before finalizing procurement decisions.

Selection Notes

Select this component when a 16-bit buffer with 5 V tolerance is required. Consider the TSSOP48 package constraints regarding board space and thermal dissipation. Evaluate the propagation delay characteristics against the system clock speed requirements to ensure timing margins are met.

Part Context

This part belongs to the 74LVC16244A series of 16-bit buffers. It shares functional similarities with other LVC family members but is distinct due to its specific 16-bit configuration and 5 V I/O tolerance. The ADGG suffix specifically denotes the TSSOP48 plastic thin shrink small outline package version.

Replacement Considerations

The 74LVCH16244ADGG is a related variant within the same product family. Verify if the additional bus hold feature present in the LVCH version is necessary for the specific application design.
