74HC4538 Datasheet (nexperia) - Dual retriggerable precision monostable multivibrator

74HC4538, Dual retriggerable precision monostable multivibrator

The 74HC4538 is a dual retriggerable-resettable monostable multivibrator.

Each multivibrator has two trigger/retrigger inputs (nA and nB), a direct reset input (nCD), two complementary outputs (nQ and nQ), and two pins (nREXT/CEXT and nCEXT) for connecting the external timing components CEXT and REX
