Counter Dividers Procurement Notes

Verify that the specific part number matches the required ceramic metal-sealed DIP-16 package configuration. Confirm compliance with radiation hardening requirements if applicable, as standard versions may differ from hardened variants. Ensure the supplier provides documentation confirming the 4000/14000/40000 series designation and valid RoHS status, noting that this specific variant is listed as non-compliant in available records. Validate the manufacturer origin as Harris Corporation to ensure authenticity.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit bidirectional counter is required with separate clock inputs for independent up and down control. The ceramic DIP-16 package is appropriate for applications necessitating high thermal stability and hermetic sealing. Consider the 2 MHz maximum frequency limit for high-speed digital designs. Verify that the CMOS input/output characteristics align with the system's voltage levels and load capacitance requirements of 50 pF.
