Philips 74HCT423
The 74HC423; 74HCT423 dual retriggerable monostable multivibrator with reset has two methods of output pulse width control. By repeating this process, the output pulse period (nQ = HIGH, nQ = LOW) can be made as long as desired. When nRD is LOW, it forces the nQ output LOW, the nQ output HIGH and also inhibits the triggering.FEATURES 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-A114F exceeds 2000 V
● MM JESD22-A115-A exceeds 200 V
● Specified from 40 C to +85 C and from 40 C to +125 C NXP Semiconductors 74HC423; 74HCT423 Dual retriggerable monostable multivibrator with reset 3. Ordering information Table 1. Ordering information Type number Package Temperature range Name
