SN74CBT16245DL

Overview

The SN74CBT16245DL is a 16-bit FET bus switch manufactured by Texas Instruments. It operates on a single power supply ranging from 4V to 5.5V and features bidirectional data transmission with low ON resistance. The device utilizes an SSOP-48 package and supports surface-mount installation. It includes -2V undershoot protection for enhanced signal integrity. The component functions as two independent 8-bit switches or one 16-bit switch, controlled by active-low enable signals.

Feature Summary

• Bidirectional 16-bit data path capability
• -2V undershoot protection included
• Low ON resistance for efficient switching

Applications

• Portable equipment requiring low voltage operation
• Battery-powered systems
• High-speed data routing

Procurement Notes

Verify the specific suffix 'DL' corresponds to the SSOP-48 tube packaging configuration. Confirm that the 4V to 5.5V operating range aligns with the target system's power supply rails. Ensure compatibility with the required control logic levels before finalizing procurement specifications.

Selection Notes

Select this component when a robust 16-bit bus switch with high noise immunity is required. The device is suitable for applications needing wide voltage flexibility between 3.3V and 5V systems. Consider the SSOP-48 footprint constraints during PCB layout planning to ensure adequate thermal dissipation and mechanical stability.
