MM74HC123AM – Reliable Dual-Pulse Timer IC

The MM74HC123AM is a dual retriggerable monostable multivibrator from onsemi/Fairchild, optimized for stable pulse generation. It runs on a wide supply range (2 V–6 V) with very low quiescent current. Both A and B inputs feature Schmitt-trigger action, allowing flexible triggering even with slow signal edges. Its pulse width is set using an external resistor and capacitor (T = R × C), giving you full control over timing. The typical propagation delay is very fast (~22 ns), making the MM74HC123AM suited for precision timing applications. In a compact 16-SOIC package, it's ideal for space-sensitive designs.
