Product details

AEC-Q100 buffer for the 3.3 V automotive bus

The Texas Instruments CLVC541AQDWRG4Q1 is an automotive-qualified (AEC-Q100) 8-bit non-inverting buffer with 3-state outputs in a 20-SOIC package.

The symmetrical 24 mA source and sink capability at the rated 2V to 3.6V supply means this buffer can drive the typical automotive CAN transceiver control lines, SPI chip-selects, or sensor interrupt lines without an external line driver. At 125°C ambient, the drive strength holds within spec — a critical margin for under-hood routing where trace impedance and temperature derating eat into signal integrity. The single-element, 8-bit-per-element architecture maps cleanly to an 8-bit data or control bus, so one package replaces eight discrete buffers.

Frequently asked questions

Can CLVC541AQDWRG4Q1 be used in 5V logic systems?

No. The supply voltage range is 2V to 3.6V. The part is not rated for 5V operation — applying 5V to the VCC pin exceeds the absolute maximum rating and will damage the device. For 5V-tolerant inputs, check the 74LVC family's 5V-tolerant variants (e.g., SN74LVC541A), but the CLVC541AQDWRG4Q1 itself is a 3.6V-max part.

What is the difference between CLVC541AQDWRG4Q1 and SN74LVC541A?

The primary difference is qualification and temperature range. Functionally, both are 8-bit non-inverting buffers with 3-state outputs in the 74LVC family, but the CLVC variant is the correct choice for automotive BOMs requiring the qualification paperwork and extended temperature range.

Where can I find the CLVC541AQDWRG4Q1 datasheet?

The datasheet is available from Texas Instruments under the device number CLVC541A. The 'QDWRG4Q1' suffix denotes the automotive-qualified, 20-SOIC, tape-and-reel variant. The datasheet covers the full family including electrical characteristics, switching waveforms, and application information for the 74LVC541A.
