Datasheet
The document describes the 74HC/HCT221 dual non-retriggerable monostable multivibrator with reset. The pulse width variance is typically less than ± 5%. The pin-out is identical to '123'. Overriding reset terminates the output pulse. The nB inputs have hysteresis for improved noise immunity. Output capability is standard (except for nREXT/CEXT). ICC category: MSI.
