It asserts both active-high and active-low push-pull reset outputs for a minimum of 140 ms after the supply rises above the threshold, holding downstream logic in reset until the rail stabilizes. This part is used in microprocessor, microcontroller, and FPGA systems requiring a clean power-on reset sequence in industrial environments from -40°C to 85°C. ## 140 ms minimum reset timeout — what it buys you The 140 ms minimum reset timeout gives the power supply and oscillator time to settle before the processor starts executing code. ## Dual reset outputs — one part, two polarities Active-high and active-low push-pull outputs on the same die mean this single supervisor can drive both an MCU reset pin (active-low) and a peripheral enable (active-high) without an external inverter. Both outputs are asserted during the timeout and de-asserted together when the timeout expires. No open-drain pull-up resistors needed — the push-pull stage drives rail-to-rail. ## Industrial temperature grade — -40°C to 85°C Rated for the -40°C to 85°C ambient range, this supervisor suits factory automation panels, outdoor telecom cabinets, and under-hood electronics where the PCB sees temperature swings. The 8-SOIC package keeps board area small while offering enough pin pitch for manual rework or inspection. ## Lifecycle and sourcing — active, no LTB risk The part is RoHS non-compliant, which may matter for EU RoHS-exempt applications or legacy BOMs where lead-bearing solder is still accepted.","metaTitle":"MAX814LESA Simple Reset/Power-On Reset IC, 140ms","metaDescription":"MAX814LESA Simple Reset/Power-On Reset IC from Maxim Integrated. 140ms minimum reset timeout, 4.7V threshold, dual active-high/active-low outputs.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active High/Active Low","Output":"Push-Pull, Push-Pull","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.7V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.3","stockQuantity":0,"priceTiers":[{"qty":37,"price":"$8.30000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/47879c97dd62a9ba599c66deebb07f03.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the exact reset timeout of MAX814LESA?","answer":"The reset timeout is 140 ms minimum. This is the guaranteed hold time the reset outputs stay asserted after the monitored voltage rises above the 4.7 V threshold."},{"question":"Can MAX814LESA be used as a direct replacement for MAX813L?","answer":"The MAX813L is a different supervisor with a 4.65 V threshold and a 200 ms timeout. The MAX814LESA uses a 4.7 V threshold and a 140 ms timeout. Verify your system's threshold tolerance and reset hold time requirements before substituting — the pinout may differ, and the timing change could affect power-up sequencing."},{"question":"Is MAX814LESA compatible with 3.3 V systems?","answer":"No — the threshold voltage is 4.7 V, designed for monitoring 5 V rails.
