The is a CMOS dual precision Monostable Multivibrator provides stable retriggerable/resettable one-shot operation for any fixed-voltage timing application. An external resistor RX and an external capacitor CX control the timing and accuracy for the circuit. Adjustment of RX and CX provides a wide range of output pulse widths from the Q and Q\ terminals. The time delay from trigger input to output transition trigger propagation delay and the time delay from RESET input to output transition are independent of RX and CX. Precision control of output pulse widths is achieved through linear CMOS techniques. Leading-edge-triggering +TR and trailing-edge-triggering -TR inputs are provided for triggering from either edge of an input pulse. An unused +TR input should be tied to VSS. An unused -TR input should be tied to VDD. A RESET on low level is provided for immediate termination of the output pulse or to prevent output pulses when power is turned on.
