SN74LVC16543DLR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC16543DLR is a 16-bit registered bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 2.7V to 3.6V and features three-state outputs. The device provides 8-bit registration on both sides, allowing for data storage at either port A or port B. It supports bidirectional data flow controlled by a direction signal and includes an output enable function. Packaged in a 56-pin SSOP format, it is designed for high-density applications requiring reliable level translation and data latching.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides 16-bit registered bus transceiver functionality with independent data latching capabilities on both ports
• Supports bidirectional data transfer between two different voltage domains within the specified operating range
• Features three-state outputs that facilitate direct connection to system buses without additional buffering

Buffers, Drivers, Receivers, Transceivers Applications

• High-density memory interface circuits requiring data registration
• Bidirectional bus architectures connecting microprocessors to peripheral devices
• System-level data buffering and isolation in embedded control units

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant and tape-and-reel specifications against the manufacturer's latest datasheet before ordering. Confirm that the 2.7V to 3.6V supply voltage requirements align with your target system design. Ensure compatibility with standard surface-mount assembly processes for the 56-pin SSOP footprint.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require simultaneous data latching and level shifting across 16 lines. It is suitable for applications needing robust bus isolation and controlled data flow direction. Consider the thermal performance and pin count relative to available board space compared to lower-density alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC16543 family of registered bus transceivers from Texas Instruments. It shares functional similarities with other LVC series logic devices but is distinct in its 16-bit width and dual-port registration capability. The device complements non-registered transceivers by providing stable data holding during bus transitions.
