Description
CD54HC221/3A dual monostable multivibrators with reset. external resistor (RX) external capacitor (CX) control timing accuracy circuit. Adjustment provides wide range output pulse widths from terminals. Pulse triggering input occurs particular voltage level related rise fall time trigger pulse. Once triggered, outputs independent further trigger inputs output pulse terminated level Reset pin. Trailing-edge-triggering leading-edge-triggering inputs provided triggering from either edge input pulse. power reset. either Mono used, each input unused device) must terminated either high low. minimum value external resistance, typically 500. minimum value external capacitance, 0pF. calculation pulse width RXCX 4.5V.
