SN74CBT16390DLR

Overview

The SN74CBT16390DLR is a 16-bit to 32-bit FET multiplexer/demultiplexer bus switch manufactured by Texas Instruments. It facilitates the connection of two separate data paths, allowing them to be multiplexed onto or demultiplexed from a common interface. The device operates within a supply voltage range of 1.65V to 3.6V and is housed in a 48-pin TSSOP package with a lead pitch of 0.5mm. It supports simultaneous addressing of memory banks for interleaving applications.

Feature Summary

• Provides 16-bit to 32-bit switching capability for high-density data path management
• Enables simultaneous access to separate memory banks through dedicated control logic
• Utilizes low on-resistance FET technology for efficient signal transmission

Applications

• Memory interleaving systems requiring simultaneous bank addressing
• High-speed data bus switching between multiple sources
• Demultiplexing data streams in complex digital interfaces

Procurement Notes

Verify component status as the SN74CBT16390DLR may be obsolete or no longer manufactured. Confirm availability through authorized distributors or check for valid replacement part numbers before procurement planning. Ensure compatibility with existing design specifications if substituting.

Selection Notes

Select this component for designs requiring 16-to-32 bit data path switching. Ensure the system operates within the specified voltage range. Consider pin count and package size constraints when integrating into the PCB layout. Verify control signal compatibility for multiplexing operations.

Part Context

This device belongs to the Texas Instruments SN74CBT series of bus switches. It is designed for applications needing efficient routing of large data buses. The DLR suffix indicates a tape and reel packaging format suitable for automated assembly processes.

Replacement Considerations

Check for active equivalents such as the SN74CBT16390DGR or other compatible 16-to-32 bit switches from Texas Instruments. Verify pinout and electrical characteristics match the original design requirements.
