Product details

That extended range covers most automotive and industrial outdoor scenarios — no need to budget for a separate commercial-grade part on the same board.

The 2V to 3.6V supply range means the CLVC540AQPWRG4Q1 works directly with 3.3V and 2.5V logic families. If your design runs a 3.3V rail, this part is plug-and-play. For 1.8V systems, look at the LVC1G or LVC2G series — this part's minimum supply is 2V.

Output drive and bus handling

The 3-state outputs let you share a data bus with other peripherals — just pull the output enable pin low to float the bus when this buffer is not selected.

Frequently asked questions

Is CLVC540AQPWRG4Q1 compatible with 3.3V logic?

Yes. The supply range of 2V to 3.6V covers 3.3V directly. The inputs are 5V-tolerant when powered at 3.3V, so you can also interface with legacy 5V logic without level shifters.

What is the closest pin-compatible alternative to CLVC540AQPWRG4Q1?

Within the same 74LVC family, the non-inverting SN74LVC541A is a common alternative if you need a non-inverting buffer. The pinout differs slightly — the 541A uses a different output enable scheme — so verify the board layout before swapping.
