The bidirectional output allows the device to both drive and be driven by the reset line, simplifying daisy-chain or shared-reset topologies. With a minimum reset timeout of 140ms, it holds the system in reset long enough for the supply and oscillator to stabilise after power-up. The SOT-143-4 package suits compact, surface-mount designs in industrial temperature environments (-40°C to 85°C). ## Where it fits in the cycle This part carries an Active lifecycle status and ROHS3 compliance, so there is no last-time-buy or obsolescence signal to manage. For a 5V rail supervisor in a SOT-143-4 footprint, it is a straightforward BOM line to qualify — no allocation pressure typical of more complex PMICs. The stock we see is franchised-origin excess, not phantom double-ordering inventory; the spot premium over book price is narrow, reflecting steady supply. For volume commitments, we quote against an RFQ with current availability confirmed at quote time.","metaTitle":"MAX6314US44D3+T Simple Reset/Power-On Reset, 4.39V Threshold","metaDescription":"MAX6314US44D3+T is a simple reset/power-on reset IC with 4.39V threshold, active-low bidirectional output, 140ms timeout.
