74AHC123AD Dual retriggerable monostable multivibrator

The 74AHC123A; 74AHCT123A is a dual retriggerable monostable multivibrator with reset. The basic output pulse width is programmed by selection of external components (REXT and CEXT). Once triggered this basic pulse width may be extended by retriggering either of the edge triggered inputs (nA or (nB).

74AHC123AD Features

* Wide supply voltage range from 2.0 V to 5.5 V

* DC triggered from active HIGH or active LOW inputs

* Retriggerable for very long pulses up to 100 % duty factor

* Direct reset terminates output pulse

* Overvoltage tolerant inputs to 5.5 V

* All inputs
