It offers the designer an economical, space-efficient solution for low supply voltage detection when used in combination with a single pullup resistor. Adding one capacitor offers the functionality of a programmable delay time after power returns. The 34064 consists of a temperature stable reference comparator with hysteresis, high-current clamping diode and open collector output stage capable of sinking up to 60mA. The MC34064's RESET output is specified to be fully functional at VIN=1V. A major improvement over competing products is the glitch-free supply current during undervoltage detection. Competing products demand a step function increase in operating current during the time that you least want or need it: during power loss. See Product Highlight below.
