Additional Details

The XR4151MD utilizes an external resistor and capacitor to set the timing interval. In monostable operation, the circuit functions as a one-shot pulse generator. The output pulse width is determined by the RC time constant. In astable operation, the circuit oscillates at a frequency determined by the two external resistors and the capacitor. The duty cycle can be adjusted by varying the ratio of the resistors.

The XR4151MD is available in a variety of packages and temperature ranges to suit different application requirements. Consult the datasheet for complete specifications and application information.
