SN74CBT16214DLR

Overview

The SN74CBT16214DLR is a 12-bit, 1-of-3 FET multiplexer/demultiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and features low on-resistance for efficient signal routing. The device supports bidirectional data flow and includes an active-low enable input to control operation. Designed for surface-mount applications, it utilizes a 48-pin SSOP package suitable for high-density PCB layouts.

Feature Summary

• Supports 1-of-3 multiplexing or demultiplexing configurations for 12-bit data paths
• Enables low on-resistance switching for minimal signal attenuation
• Features an active-low enable pin for precise control over data path activation

Applications

• High-speed data bus switching in communication systems
• Signal routing in embedded processing units
• Multiplexing sensor data lines in industrial control interfaces

Procurement Notes

Verify the specific suffix 'DLR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the operating temperature range aligns with the target environmental conditions. Ensure compatibility with the system's logic voltage levels before integration into the design.

Selection Notes

Select this component when a 12-bit wide data path requires selection among three distinct sources or destinations. The 1-of-3 architecture offers more flexibility than standard 1-of-2 switches. Consider the 48-pin SSOP footprint for space-constrained designs requiring high channel density.

Part Context

This part belongs to the SN74CBT1621x family of analog switches and multiplexers. These devices are engineered for high-speed digital applications requiring low distortion and fast switching times. The family provides various bit-width options to accommodate different data bus architectures.

Replacement Considerations

Check for direct equivalents within the SN74CBT1621x series from Texas Instruments. Verify pinout compatibility and electrical specifications against alternative manufacturers' offerings before substitution.
