SN74CBT16292DGGR

Overview

The SN74CBT16292DGGR is a Texas Instruments integrated circuit belonging to the 74CBT logic series. It functions as a 12-bit 1-of-2 FET multiplexer/demultiplexer housed in a 56-TVSOP package. The device operates on a single power supply ranging from 4.5V to 5.5V and supports an operating temperature range of -40°C to +85°C. Key electrical parameters include a maximum propagation delay of 3.4ns at 5V and low on-resistance characteristics typical of the CBT family. The component is RoHS compliant and classified under ECCN EAR99.

Feature Summary

• Integrates twelve independent analog switches configured for 1-of-2 multiplexing or demultiplexing operations
• Features internal pull-down resistors on all inputs to ensure defined logic states when unconnected
• Utilizes FET technology to provide low on-resistance and minimal signal distortion
• Supports surface-mount installation in a compact 56-terminal thin very small outline package

Applications

• High-speed data routing in telecommunications equipment
• Signal selection in computer peripheral interfaces
• Multiplexing in industrial control systems
• Data bus switching in consumer electronics

Procurement Notes

Verify the specific suffix 'DGGR' against official Texas Instruments documentation to confirm the tape and reel packaging configuration, as the provided reference material primarily lists the 'DGVR' variant. Ensure the procurement order explicitly matches the requested package style and quantity format to avoid fulfillment discrepancies. Cross-reference the manufacturer part number with current datasheets to validate active status and any recent product change notices.

Selection Notes

Select this component when designing circuits requiring 12-channel signal routing within a 5V logic environment. The choice is appropriate for applications demanding low propagation delay and high bandwidth. Consider the TVSOP package constraints regarding thermal dissipation and board space. Verify that the system voltage remains strictly within the 4.5V to 5.5V operational limits to ensure reliable performance.

Part Context

This device is part of the broader 74CBT family of low-voltage CMOS logic components designed for high-speed switching applications. While similar to the SN74CBTLV16292 which operates at lower voltages, this specific model targets standard 5V systems. It shares functional similarities with other 12-bit muxes but distinguishes itself through its specific voltage tolerance and pinout configuration suitable for dense PCB layouts.
