SN74CBT16245CDLR

Overview

The SN74CBT16245CDLR is a 16-bit FET bus switch manufactured by Texas Instruments. It operates within a supply voltage range of 4V to 5.5V and supports bidirectional data transmission. The device features an SSOP-48 package with a maximum propagation delay of 150 ps and a maximum on-resistance of 12 ohms. It includes -2 V undershoot protection and functions as a non-inverting buffer/driver with three-state outputs, suitable for high-speed digital applications.

Feature Summary

• Provides 16-bit bidirectional data switching capability
• Features low on-resistance for efficient signal transmission
• Includes protection against negative voltage undershoot
• Supports standard surface-mount installation

Applications

• High-speed data routing in electronic systems
• Buffering and driving digital signals
• Voltage level translation between 3.3V and 5V domains

Procurement Notes

Verify the specific suffix 'CDLR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the required 4V to 5.5V operating voltage range. Check for any recent product change notifications or lifecycle status updates from Texas Instruments before finalizing procurement plans.

Selection Notes

Select this component when a 16-bit wide bus switch is required for 5V logic systems. It is appropriate for designs needing fast switching speeds with minimal signal distortion. Consider the SSOP-48 footprint constraints during PCB layout. Verify that the system voltage does not exceed the maximum rating to ensure reliable operation.

Part Context

This part belongs to the SN74CBT series of bus switches, designed for high-speed performance. It serves as a digital interface component for managing data flow between different sections of a circuit board. The device is distinct from transceivers by its specific focus on switching rather than voltage translation alone.

Replacement Considerations

The SN74CBT16245CDGGR is listed as a manufacturer-recommended alternative. Verify pinout compatibility and package dimensions before substitution.
