Product details

The 8-SOIC package (0.154" width) fits a standard supervisor footprint and is surface-mount for automated assembly.

Dual output polarity — one part, two logic families

The MAX814KESA asserts both Active High and Active Low outputs from the same die, covering both reset polarities in a single BOM line.

140ms reset timeout — why that window matters

For a typical MCU with a 10ms startup sequence, 140ms gives a comfortable margin. It also prevents spurious resets from short supply glitches that last tens of milliseconds.

The part is RoHS non-compliant per the listing.

Frequently asked questions

What is the exact reset threshold voltage of MAX814KESA?

The reset threshold voltage is 4.8V. This is the voltage at which the device asserts a reset on the monitored 5V rail.

Can MAX814KESA be used as a direct replacement for MAX814LESA?

The MAX814LESA is a same-function sibling, but its reset threshold voltage differs. Confirm the threshold matches your rail voltage before substituting. The pinout and package are identical, so it is a mechanical fit.

Is MAX814KESA compatible with 5V logic?

Yes. The 4.8V threshold is designed for a 5V supply rail, and the push-pull outputs swing rail-to-rail, making it directly compatible with 5V logic families.

Is MAX814KESA available in tape and reel packaging?

The listing shows the package form as Bulk. Tape and reel availability may exist through alternate order codes or distributor re-reeling; confirm at quote time.
