Product Summary

The SNJ54LS590 is a 8-bit binary counter with input register, which comes in a 16-pin package and consists of a parallel input, 8-bit storage register feeding an 8-bit binary counter. Both the register and the counter have individual positive-adge-triggered clocks. In addition, the SNJ54LS590 has direct load and clear functions. A low-going RCO pulse will be obtained when the counter reaches the hex word FF.
