Description:

Dual 4-bit decade counters.

HD74HC490, Dual 4-bit Decade Counters

This circuit contains eight master-slave flip-flops and additional gating to implement two individual 4-bit decade counters.

Each decade counter has individual clock, clear and set-to-9 inputs.

BCD count sequences of any length up to divide-by-100 may be implemented with a single HD74HC490.
