SN74CBT16232DL

Overview

The SN74CBT16232DL is a synchronous 16-bit 1-of-2 FET multiplexer/demultiplexer designed for applications requiring two separate data paths. It features an input/output voltage maximum of 5.5 V and operates within a temperature range of -40 to 85 °C. The device supports a maximum input/output continuous current of 128 mA and exhibits a typical input/output OFF-state capacitance of 4 pF. Packaged in a 56-pin SSOP, it functions as a digital bus switch IC.

Feature Summary

• Synchronous operation for precise timing control in data path switching
• Low OFF-state capacitance to minimize signal distortion
• High continuous current handling capability for robust signal transmission

Applications

• Data path switching between two separate sources
• Digital bus switch implementations
• Multiplexing and demultiplexing signals in high-speed interfaces

Procurement Notes

Verify the package type matches the required PCB footprint, specifically the 56-pin SSOP configuration. Confirm the operating temperature range meets system environmental requirements. Ensure the supply voltage does not exceed the 5.5 V maximum rating. Check for specific ordering suffixes if different tape-and-reel options are needed.

Selection Notes

Select this component when synchronous 16-bit switching is required with low capacitance characteristics. It is suitable for systems needing high current drive capabilities up to 128 mA. Consider the 56-pin SSOP package constraints during layout design. Evaluate the -40 to 85 °C operating range against application thermal conditions.

Part Context

This part belongs to Texas Instruments' CBTCB series of synchronous bus switches. It is distinct from asynchronous variants by its clocked control mechanism. The device integrates 16 independent channels into a single package, offering a compact solution for complex data routing tasks compared to discrete transistor arrangements.

Replacement Considerations

The SN74CBT16232DLR is a reel-based variant of the same functional device. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement maintains the synchronous control logic and 56-pin SSOP form factor.
