CD74HC123M - Brand New TI Monostable Multivibrators
-
Description
The CD74HC123M is a dual monostable multivibrator with resets, used in electronic circuits to generate the output pulse of known duration. This electronic component is manufactured by Harris and has four different variations: CD74HC123, CD74HCT123, CD74HC423, and CD74HCT423. The CD74HCT123 and CD74HCT423 are retriggerable, while the CD74HC123 and CD74HC423 have additional features to trigger with negative to positive reset pulse that allows to work well with the electronic circuits. Adjusting the external resistors and capacitors provides wide ranges of output pulse widths for the Q and Q terminals, and the triggering also occurs at a particular voltage level from the leading or trailing edge.
