SN74LVT16543DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVT16543DLR 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 utilizes LVT logic series technology and includes latched transceiver functionality with independent output enable control for each direction. It is housed in a 56-pin SSOP package, supports surface mount installation, and maintains an operating temperature range from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transfer between two buses with registered storage capability
• Features independent output enable control for each transmission direction
• Supports low-voltage operation compatible with LVTTL input and output levels

Buffers, Drivers, Receivers, Transceivers Applications

• High-density memory mapping systems
• Clock drivers and buffered interfaces
• Bus-oriented architectures requiring registered data holding

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DLR' confirms the tape-and-reel packaging format distinct from tube-packaged variants like 'DLG4'. Ensure the design accommodates the 56-SSOP footprint dimensions and thermal requirements. Confirm that the 2.7V to 3.6V supply rail aligns with the target system's power distribution network before finalizing component selection.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit width with internal registration is required for bus isolation. Compare propagation delay specifications against system timing constraints. Verify that the LVT logic family compatibility matches the driving and receiving devices in the circuit architecture to ensure signal integrity across the interface.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVT16543 family of 16-bit registered transceivers. It shares functional similarities with other ABT and ALVT series devices but is optimized for lower voltage applications. The DL suffix indicates the SSOP package type, while the R suffix specifies the reel packaging configuration for automated assembly processes.
