74HC423 Datasheet and Specifications PDF

74HC423; 74HCT423 are high-speed Si-gate CMOS devices that are pin compatible with Low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC423; 74HCT423 du.

and benefits
* DC triggered from active HIGH or active LOW inputs
* Retriggerable for very long pulses up to 100 % duty factor
* Direct reset terminates output pulse
* Schmitt-trigger action on all inputs except for the reset input
* Complies with JEDEC standard no. 7A
* ESD protection:
* HBM JESD22.

The ’HC123, ’HCT123, CD74HC423 and CD74HCT423 are dual monostable multivibrators with resets. They are all retriggerable and differ only in that the 123 types can be triggered by a negative to positiv.

* Overriding Reset Terminates Output Pulse
* Triggering From the Leading or Trailing Edge
* Q and Q Buffered Outputs
* Separate Resets
* Wide Range of Output-Pulse Widths
* Schmitt Trigger on Both A and B Inputs
* Fanout (Over Temperature Range) - Standard Outputs . . . . . . . . . . . . . . . 10 LS.

The 74HC423 is a dual retriggerable monostable multivibrator with output pulse width control by two methods. The basic pulse time is programmed by selection of an external resistor (REXT) and capacito.
