CMOS Dual Precision Monostable Multivibrator
CD14538BMS dual precision monostable multivibrator provides stable retriggerable/resettable one-shot operation fixed-voltage timing application. external resistor (RX) external capacitor (CX) control timing accuracy circuit. Adjustment provides wide range output pulse widths from terminals. time delay from trigger input output transition (trigger propagation delay) time delay from reset input output transition (reset propagation delay) independent Precision control output pulse widths achieved through linear CMOS techniques. Leading-edge-triggering (+TR) trailing-edge-triggering (-TR) inputs provided triggering from either edge input pulse. unused input should tied VSS. unused input should tied VDD. RESET level) provided immediate termination output pulse prevent output pulses when power turned unused RESET input should tied VDD. However, entire section CD14538BMS used, inputs must tied either VSS. Table normal operation circuit retriggers (extends output pulse period) application each trigger pulse. operation non-retriggerable mode, connected when leading-edge triggering (+TR) used connected when trailing-edge triggering (-TR) used. time period this multivibrator calculated RXCX. minimum value external resistance, minimum maximum values external capacitance, 100µF, respectively. CD14538BMS interchangeable with type MC14538 similar pin-compatible with CD4098B* CD4538B**.
