SN74CBT16390DGGR

Overview

The SN74CBT16390DGGR is a 16-bit to 32-bit FET multiplexer/demultiplexer bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and supports an operational temperature range from -40°C to +85°C. The component is housed in a 56-pin TSSOP package with a tape-and-reel configuration, designed for applications requiring two separate data paths to be multiplexed onto or demultiplexed.

Feature Summary

• Provides 16-bit to 32-bit switching capability for dual data path management
• Utilizes FET technology for efficient signal routing
• Supports standard 5V logic operation levels

Applications

• Multiplexing two separate data paths onto a single output
• Demultiplexing signals from one input to two separate outputs
• High-speed bus switching applications

Procurement Notes

Verify the specific suffix DGGR confirms the 56-pin TSSOP package and tape-and-reel packaging format. Ensure the operating environment remains within the specified -40°C to +85°C temperature range and that the supply voltage stays between 4.5V and 5.5V to maintain device integrity and performance specifications.

Selection Notes

Select this component when a high-density solution is required for managing dual data paths in a compact form factor. The 56-pin TSSOP package offers surface-mount convenience. Confirm that the 4.5V to 5.5V supply requirement aligns with the system's power architecture before integration into the design.

Part Context

This part belongs to the SN74CBT16390 series of bus switches. It is distinct from decoder chips like the SN74HC139N or other transceivers such as the SN74AVC16T245. The device is specifically engineered for multiplexing and demultiplexing functions rather than general-purpose logic decoding or voltage level translation.

Replacement Considerations

The SN74CBT16390DGG is a verified substitute offering identical functionality in a non-reel SOP package. Verify pin compatibility and package dimensions when substituting the reel version (DGGR) with the tube version (DGG).
