74LVT16244BDGG,112

Overview

The Nexperia 74LVT16244BDGG,112 is a 3.3 V 16-bit buffer and line driver featuring 3-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V and supports overvoltage tolerant inputs up to 5.5 V. The device utilizes BiCMOS technology for high-speed performance and provides an output capability of +64 mA and -32 mA. It includes bus hold data inputs to eliminate external pull-up resistors and features IOFF circuitry for partial power-down mode operation.

Feature Summary

• Features four independent output enables controlling groups of three-state outputs.
• Includes bus hold data inputs to maintain unused input states without external components.
• Supports live insertion and extraction with no bus current loading when tied to a 5 V bus.
• Provides IOFF circuitry to disable outputs during partial power-down conditions.

Applications

• High-speed 16-bit bus interface systems
• Mixed 3.3 V and 5 V logic environments
• Buffering applications requiring direct TTL level interfacing

Procurement Notes

Verify the specific ordering suffix

Selection Notes

Select this component for designs requiring a 16-bit non-inverting buffer with high drive strength. Ensure the system operates between 2.7 V and 3.6 V. Consider the TSSOP48 package constraints and verify that the required propagation delay fits within the timing budget of the target bus architecture.

Part Context

This part belongs to the 74LVT family of logic devices manufactured by Nexperia. It is functionally compatible with other 16-bit buffers in the series but offers specific BiCMOS speed characteristics. The BDGG suffix indicates the TSSOP48 plastic thin shrink small outline package variant designed for surface-mount assembly.

Replacement Considerations

The 74LVTH16244BDGG is a related variant within the same datasheet. Verify if the specific LVTH characteristics are required or if the standard LVT version suffices for the application requirements.
