The TC74WH123 is high speed CMOS MONOSTABLE MULTIVIBRATORfabricated with silicon gate C2MOS technology. There are two trigger inputs, A input (Negative edge), and B input (Positive edge). These inputs are valid for a slow rise/fall time signal (tr =tf = lsec.) as they are schmitt trigger inputs. This device may also be triggered by using ~LR input (Positive edge). After triggering. the output stays in a MONOSTABLE state for a time period determined by the external resistor and capacitor (Rx, Cx). A low level at the ~LR input breaks this state. Limits for Cx and Rx are : External capacitor, Cx ..*.... No limit External resistor, Rx .**...**... VCC = 2.OV more than 5kfl VCC> 3.OV more than ikfl An input protection circuit ensures that o t0 7V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V t0 3V systems and two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.
