CLVC541AQDWRG4Q1

Overview

The CLVC541AQDWRG4Q1 is an automotive-grade octal buffer and line driver from Texas Instruments, belonging to the SN74LVC541A-Q1 series. It features eight non-inverting inputs and outputs with three-state capability, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 2 V to 3.6 V and supports output currents of 24 mA at both high and low states. It exhibits propagation delays of 5.6 ns at 2.7 V and 5.1 ns at 3.3 V, with a maximum operating temperature of +125°C and AEC-Q100 qualification.

Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards for extended thermal endurance up to 125°C
• Octal configuration providing eight independent non-inverting signal paths with three-state output control
• Low static current consumption of 10 uA to support energy-efficient system designs

Applications

• Automotive electronic systems requiring robust signal buffering
• High-speed data bus architectures utilizing LVC logic families
• Industrial control interfaces demanding wide operating temperature ranges

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number CLVC541AQDWRG4Q1 with official Texas Instruments documentation. Confirm that the specific suffix indicates the correct SOIC-20 packaging and reel quantity specifications. Ensure compliance with RoHS directives and check for any recent production change notices affecting material composition or assembly origin before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require high-drive capability for multiple parallel lines within automotive environments. The LVC logic family ensures compatibility with standard CMOS and TTL input levels while maintaining low power dissipation. Consider the 20-pin SOIC footprint for PCB layout constraints and verify that the 2V to 3.6V supply range aligns with the target system's power architecture.

Part Context

This device is part of the broader SN74LVC541A-Q1 family of octal buffers designed specifically for automotive applications. It shares functional similarities with other LVC series components but is distinguished by its specific AEC-Q100 qualification and optimized performance characteristics for harsh environmental conditions. The Q1 suffix denotes its adherence to automotive quality standards, differentiating it from commercial grade equivalents.

Replacement Considerations

Direct replacements must match the SN74LVC541A-Q1 specification, including AEC-Q100 certification and SOIC-20 packaging. Verify pinout compatibility and electrical parameters such as propagation delay and output current drive capabilities to ensure seamless integration without circuit redesign.
