What the MAX814KCSA+ does on your board
The output is push-pull, configurable as active-high or active-low, which means it can drive the reset input of most microcontrollers, FPGAs, or DSPs without an external pull-up resistor. The 8-SOIC package fits standard footprints and is surface-mount, so it goes through reflow alongside other SMD passives. The 0°C to 70°C commercial temperature range suits indoor equipment like office peripherals, test instruments, or telecom line cards in conditioned racks. It is not rated for under-hood automotive or outdoor enclosures where the ambient may push past 70°C.
Lifecycle and sourcing posture
ROHS3 compliant, so it meets the latest EU restriction requirements for lead-free assembly.
Integration note — reset polarity and timeout
Because the reset can be wired as active-high or active-low, confirm the polarity your processor expects before layout. The 140ms minimum timeout is long enough for most MCUs to complete their power-up sequence, but if your processor needs a longer reset pulse, you may need an external RC delay or a supervisor with a programmable timeout.
