| Description | The M74HC123 is an high speed CMOS c MONOSTABLE MULTIVIBRATOR fabricated with u silicon gate C2MOS technology. d There are two trigger inputs, A INPUT (negative ro edge) and B INPUT (positive edge). These inputs P are valid for slow rising/falling signals, (tr=tf=l sec). te The device may also be triggered by using the CLR input (positive-edge) because of th. |

period determined by the external resistor Rx and capacitor Cx. When Cx > 10nF and Rx > 10KΩ, the output pulse width value is approsimatively given by the formula : tW(OUT) = K · Cx · Rx. (K ≅ 0.45). Taking CLR low breaks this MONOSTABLE STATE. If the next trigger pulse occurs during the MONOSTABLE period it makes the MONOSTABLE period longer. Limit for values of Cx and Rx : Cx : N. |
