... MXD1818 also keep reset asserted for at least 100ms after the output is momentarily pulled to GND by an external push-button switch. The MXD1812/MXD1817 have an active-high push-pull RESET output. The MXD1810/MXD1815 (push-pull) and MXD1811/MXD1813/MXD1816/MD1818 (open-drain) have an active-low RESET output. The open-drain devices (MXD1811/MXD1813/MXD1816/MXD1818) have an internal pullup resistor to V ...

... GND Detailed Description RESET /RESET Output A microprocessor’s (µP’s) reset input starts the micro- processor in a known state. The MXD1810–MXD1813/ MXD1815–MXD1818 µP supervisory circuits assert reset to prevent code-execution errors during power- up, power-down, and brownout conditions (Figure 4). Whenever V falls below the reset threshold, the reset CC output asserts ...

... High-impedance CMOS- logic inputs connected to the RESET/RESET pin can drift to indeterminate voltages. This does not present a problem in most cases, since most µPs and circuitry do not operate at V below +1V. For MXD1810/ CC MXD1815 applications where RESET must be valid down adding a pulldown resistor between ...
