CLVC244AQDWRG4Q1

Overview

The CLVC244AQDWRG4Q1 is an automotive-grade octal buffer and line driver from Texas Instruments, belonging to the SN74LVC244A series. It features eight non-inverting channels with three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 1.65 V to 3.6 V. Key electrical parameters include a maximum high-level output current of -24 mA and a low-level output current of 24 mA. Propagation delay is specified at 6.7 ns at 2.7 V and 5.7 ns at 3.3 V. It is qualified under AEC-Q100 standards for operation between -40°C and +125°C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
• Low-voltage CMOS technology enabling efficient operation across a wide supply voltage range.
• Three-state outputs allow direct connection to bus lines for improved system flexibility.

Applications

• Automotive memory mapping systems
• Clock buffering and distribution circuits
• Bus-oriented transmissions

Procurement Notes

Verify the specific suffix G4 indicates lead-free RoHS compliance and the Q1 suffix confirms automotive grade status. Confirm the SOIC-20 package dimensions match the design footprint. Ensure the order quantity aligns with the reel packaging specifications provided by the manufacturer. Cross-reference the datasheet revision date to ensure compatibility with current design requirements.

Selection Notes

Select this component when designing for automotive applications requiring robust signal integrity and low power consumption. The LVC family offers superior switching speeds compared to standard HC logic while maintaining compatibility with 3.3V and 5V systems. Consider the thermal performance of the SOIC-20 package if operating near the upper temperature limits.

Part Context

This part is part of the broader SN74LVC244A family of octal buffers. It shares functional similarities with other automotive-qualified logic devices but is distinguished by its specific low-voltage characteristics and drive strength. It serves as a critical interface component in digital systems requiring isolation or signal amplification.

Replacement Considerations

The SN74LVC244ADWG4 is a non-automotive equivalent with identical logical functionality and pinout. Verify that the reduced temperature range and lack of AEC-Q100 qualification meet the specific application requirements before substitution.
