The HCC/HCF4538B dual precision monostable multivibrator provides stable retriggerable/resettable one-shot operation for any fixedvoltage 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...
