Functional Description

The CD74HCT423M96G4 device features two independent monostable multivibrators with retriggerable functionality. Each multivibrator has an active-low trigger input (A) and an active-high trigger input (B), an output (Q) and its complement (Q'), and an external capacitor (Cext) and external resistor (Rext) that determine the output pulse width. The retriggerable design means that additional pulses on the trigger inputs can extend the output pulse duration, allowing for flexible timing adjustments.
