SN54LS390J Description

Short technical summary and product information.

The SN54LS390J is a dual 4-bit decade and binary counter IC manufactured by Motorola Semiconductor. This component integrates eight master-slave flip-flops and additional gating to create two independent four-bit counters within a single package. It is designed to implement dual divide-by-two and divide-by-five counters, enabling cycle lengths up to divide-by-100 when combined.

 

Key electrical characteristics include a typical maximum count frequency of 35 MHz. The device is housed in a 16-pin CDIP (J) package, suitable for through-hole mounting. It operates reliably within a temperature range of -55°C to 125°C, making it suitable for demanding environmental conditions.

 

This counter IC offers parallel outputs from each stage, providing sub-multiple input count frequencies for system timing signals. Its dual 4-bit configuration can significantly improve system densities by reducing the overall counter package count. The SN54LS390J is characterized for operation over the full military temperature range.
