General part information

MAX709 Series

The MAX709 provides a system reset during power-up, power-down, and brownout conditions. When VCCfalls below the reset threshold, RESET goes low and holds the µP in reset for 140ms min after VCCrises above the threshold.The RESET output is guaranteed to be in the correct state with VCCdown to 1V. The MAX709 provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, or +3V powered systems. The MAX709 is available 8-pin DIP, µMAX®, and SO packages.ApplicationsMinimum Component Count, Low-Cost Processor Systems
