The CD4538BC is a dual, precision monostable multivibratorwith independent trigger and reset controls. The deviceis retriggerable and resettable, and the control inputs areinternally latched. Two trigger inputs are provided to alloweither rising or falling edge triggering. The reset inputs areactive LOW and prevent triggering while active. Precisecontrol of output pulse-width has been achieved using linearCMOS techniques. The pulse duration and accuracyare determined by external components RX and CX. Thedevice does not allow the timing capacitor to dischargethrough the timing pin on power-down condition. For thisreason, no external protection resistor is required in serieswith the timing pin. Input protection from static discharge isprovided on all pins.
