The SN54LS390J from Texas Instruments is a dual 4-bit decade and binary counter integrated circuit. This component contains eight master-slave flip-flops and additional gating to implement two independent four-bit counters within a single package. It is designed to provide dual divide-by-two and divide-by-five counters, enabling cycle lengths up to divide-by-100 when configured as a bi-quinary counter.
Key electrical characteristics include a typical maximum count frequency of 35 MHz. The device features buffered outputs to reduce the possibility of collector commutation. The SN54LS390J is specified for operation over the full military temperature range of -55°C to 125°C.
Packaged in a 16-pin CDIP (J) configuration, this component is suitable for through-hole mounting. The dual 4-bit counter design can significantly improve system densities by reducing the overall counter package count. Parallel outputs from each counter stage provide submultiple input count frequencies for system-timing signals.
