74VHC123AFT(BJ)

74VHC123AFT(BJ) is a CMOS digital silicon monolithic IC. It is a CMOS monostable multivibrator fabricated with silicon gate C²MOS technology. There are two trigger inputs, active-low A input (negative edge), and B input (positive edge). These inputs are valid for a slow rise/fall time signal (tr = tf = 1 s) as they are schmitt trigger inputs. This device may also be triggered by using active-low CLR input (positive edge). An input protection circuit ensures that 0 to 5.5V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery back-up. This circuit prevents device destruction due to mismatched supply and input voltages.
