SN74CB3Q16245DLR

Overview

The SN74CB3Q16245DLR is a 16-bit bus switch manufactured by Texas Instruments, designed for automotive applications. It operates within a supply voltage range of 2.3 V to 3.6 V and supports an operating temperature from -40°C to +85°C. The device features a maximum on-resistance of 9 Ohms and a propagation delay of 150 ps. It is housed in a 48-SSOP package with a width of 7.50 mm.

Feature Summary

• Automotive qualification compliant
• Low on-resistance for signal integrity
• High-speed switching capability

Applications

• Automotive electronic systems
• Data bus protection
• Signal routing in vehicles

Procurement Notes

Verify the specific suffix 'DLR' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure the component meets AEC-Q100 standards if required for your automotive design. Cross-reference the ordering information directly with Texas Instruments official documentation to avoid discrepancies.

Selection Notes

Select this component when low on-resistance and high-speed performance are critical for 16-bit data buses in automotive environments. The 2.3 V to 3.6 V supply range suits lower voltage logic systems. Consider the 48-SSOP package constraints for PCB layout and thermal management requirements during the design phase.

Part Context

This part belongs to the SN74CB3Q series of automotive-grade bus switches. It provides 16 channels of bidirectional data transfer. The series is characterized by low on-resistance and fast switching speeds, making it suitable for high-frequency applications requiring reliable signal transmission in harsh automotive conditions.

Replacement Considerations

SN74CB3Q16245DGGR is a recommended manufacturer substitute offering identical functionality in a TSSOP-48 package.
