circuit. Therefore, high-impedance CMOS logic inputs connected to RESET can drift to undetermined

voltages. This presents no problem in most applications, since most

μP and other circuitry is inoperative

resistor is needed from RESET pin to GND as shown in Figure 4, then RESET output will be held at low

state. The resistor’s value is not critical, it should be about 100KΩ, large enough not to load RESET, small

enough to pull RESET to ground.
