The MC74HC390AFELG is a dual 4-bit decade ripple counter that counts up to 99 in binary-coded decimal (BCD) format. It operates by incrementing the count on each rising edge of the clock input. The counters can be reset asynchronously using the master reset input, which sets all outputs to zero.
These alternative models offer similar functionality and can be considered as substitutes for the MC74HC390AFELG depending on specific requirements.
