Reset timeout is 140ms minimum, giving the downstream processor enough time to stabilize after the supply crosses the threshold on power-up. ## 8-SOIC package and reflow considerations Housed in an 8-SOIC package (0.154\" body width, 3.90mm), the MAX818LESA uses a standard footprint that places cleanly with no tombstoning risk on a typical reflow profile. ## Active lifecycle and RoHS status RoHS non-compliant per the manufacturer's designation, so check your assembly's exemption allowance before committing to a BOM that requires full RoHS conformance.","metaTitle":"MAX818LESA Analog Devices Supervisor IC, 4.65V Threshold","metaDescription":"MAX818LESA supervisor IC from Analog Devices.
