Counter Dividers Procurement Notes

Verify the specific manufacturer source, as documentation references both Quality Semiconductor and IDT/Renesas. Confirm RoHS compliance status, as some sources indicate lead-free while others note non-compliance. Ensure the package type matches the required CQCC20 footprint. Check product status, as listings may indicate obsolete availability. Validate electrical specifications against the official datasheet before integration.

Counter Dividers Selection Notes

Select this component for applications requiring a 4-bit synchronous binary counter with positive edge triggering. It is suitable for designs needing asynchronous reset and bidirectional bus switching capabilities. Consider the CQCC20 ceramic package for environments requiring robust sealing. Verify compatibility with 5 V logic levels and ensure the operating temperature range meets system requirements. Compare performance metrics against alternative FCT series counters if higher bit depth is needed.
