SN74CBT16209ADL

Overview

The SN74CBT16209ADL is an 18-bit FET bus-exchange switch manufactured by Texas Instruments. It provides high-speed TTL-compatible bus switching or exchanging capabilities with a bandwidth of 200 MHz. The device supports input/output voltages up to a maximum of 5.5 V. It is housed in a 56-SSOP package and operates within a temperature range of -40°C to +85°C. This component functions as a universal bus exchanger, facilitating efficient data routing in digital systems.

Feature Summary

• Provides 18 bits of high-speed bus switching functionality
• Supports TTL-compatible logic levels for broad interface compatibility
• Features low on-resistance FET switches for minimal signal distortion
• Enables flexible crosspoint and exchange configurations

Applications

• High-speed data routing in telecommunications equipment
• Bus arbitration and switching in computer systems
• Signal path selection in test and measurement instruments
• Data exchange interfaces in industrial automation controllers

Procurement Notes

Verify the specific suffix 'DL' confirms the 56-SSOP package variant when sourcing. Ensure the revision level matches your design requirements, as TI may update documentation without changing the part number immediately. Confirm that the 5.5 V absolute maximum rating aligns with your system's voltage rails to prevent damage. Check for any RoHS compliance markings if environmental regulations apply to your deployment.

Selection Notes

Select this component when an 18-bit wide bus exchange is required with high bandwidth. It is suitable for applications needing TTL compatibility and robust signal integrity. Consider the 56-SSOP package constraints for PCB layout. Evaluate if the 200 MHz bandwidth meets your signal frequency needs. Compare against other CBT series devices if fewer bits or different voltage tolerances are sufficient for your design.

Part Context

This device belongs to Texas Instruments' CBT series of high-performance analog switches. It is designed for demanding digital applications requiring fast switching speeds and low power consumption. The SN74CBT16209A variant offers enhanced performance over previous generations. It complements other bus switching solutions in TI's portfolio for complex system architectures.
