... DETAILED DESCRIPTION The UTC 83CXXX have a push-pull output stage. A microprocessor’s (µP’s) reset input initiates the microprocessor in a known state. The UTC 83CXXX assert a reset signal as long as the V drops below a preset threshold. When V 140ms. They have a function of preventing code-execution errors during power-up, power-down, or brownout conditions by resetting ...

... APPLICATION INFORMATION 1. Ensuring a Valid Reset Output Down to V The UTC 83CXXX RESET output no more sinks current when V circuit. Therefore, high-impedance CMOS logic input connected to RESET can drift to undetermined voltages. This presents no problem in most applications since most microprocessors and other circuitry can’t be operated when V is under 1V. In figure 1, however, in applications where RESET must be valid down to 0V. In order to causes any stray leakage currents to flow to ground, adding a pull-down resistor to RESET , that holding RESET low. (R1’ ...
