As a decade counter, it cycles through ten output states (0–9) on each clock pulse, making it suitable for digital displays, event counting, and time-base generation in industrial control or instrumentation.
Plan for manual or tube-fed placement; not compatible with standard pick-and-place feeders without a tube adapter.
No — the 54190DM is listed as RoHS non-compliant. It contains lead in the solder finish. Check your regional exemption (e.g., RoHS Annex III for high-reliability or military applications) before ordering.
The 54190DM is a synchronous decade up/down counter. Typical applications include digital frequency dividers, event counters in industrial controllers, and BCD output for seven-segment displays. It counts from 0 to 9 on each clock cycle and can count up or down under logic control.
