SN74LVTH16646DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVTH16646DLR is a 16-bit registered bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 3.6 V and features three-state outputs. The device integrates registers that allow data on the A or B bus to be clocked into storage, supporting multiplexed transmission of either registered or real-time data via a select input. It utilizes an SSOP-56 package and is designed for surface-mount installation with independent direction control.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrates 16-bit registers to capture and store bus data upon clocking

• System-level interconnects needing isolated registered data paths

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the active status with official Texas Instruments channels to avoid obsolete stock. Confirm thermal performance matches your system's dissipation limits.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 3.3-V logic family interface requires both bus driving capability and internal data latching. The LVTH series offers BiCMOS performance suitable for high-speed applications. Consider the SSOP-56 footprint constraints during PCB layout. Verify that the required propagation delay and drive strength align with the target bus timing specifications.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVTH16646 family of registered bus transceivers. It serves as a bridge between microprocessors and peripheral devices where data integrity and timing alignment are critical. The registered nature distinguishes it from standard unregistered transceivers by providing stable output states independent of input fluctuations after the clock edge.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74ACT16646DLR or SN74ABT16646DLR if voltage compatibility allows. Verify pinout and functional equivalence before substitution. Ensure the alternative supports the same 3.3-V operating range and register functionality.
