Product details

Active high output — confirm polarity before layout

Active high reset is less common than active low; many processors expect a logic-low during reset. Before committing the BOM line, verify that the target processor's reset input is active high — or plan an external inverter. The push-pull output eliminates the need for an external pull-up resistor, saving one component per board.

Housed in a SOT-143-4 surface-mount package, this part occupies minimal board area. The four-pin footprint is standard and easy to route.

Frequently asked questions

Is MAX6803US46D3+T active high or active low?

It is active high. The push-pull output goes high during reset, so confirm your processor's reset input polarity before using this part.

What package type is MAX6803US46D3+T available in?

It is supplied in a SOT-143-4 surface-mount package (also designated TO-253AA). The part ships in tape-and-reel packaging.
