Additional Details:
The output pulse width of the CD4528BMJ/883QS is determined by an external resistor and capacitor. The retriggerable feature allows for extending the output pulse as long as the input is triggered before the timeout period. The device is housed in a ceramic DIP package. The military-grade designation ensures that the device has undergone rigorous testing and screening to meet stringent quality standards. It's typically used in applications where long-term reliability and performance are critical, such as in aerospace, defense, and industrial control systems. Proper decoupling capacitors should be used near the power supply pins to minimize noise and ensure stable operation.
