... B, transition triggered input, either of which can be used as an inhibit input. Also included is a clear input that when taken low resets the one shot. The MM74HC4538 is retriggerable. That is, it may be triggered repeatedly while their outputs are generating a pulse and the pulse will be extended ...

... In addition, the output of the trigger-control reset circuit is LOW. TRIGGER OPERATION The MM74HC4538 is triggered by either a rising-edge sig- nal at input A (# falling-edge signal at input B (#8), with the unused trigger input and the Reset input held at the voltage levels shown in the Truth Table. Either trigger ...
