Product Summary

The N82S123N is the field programmable EPROM, which means that custom patterns are immediately available by following the Signetics Generic I fusing procedure. The N82S123N is supplied with all outputs at logic Low. Outputs are programmed to a logic High level at any specified to a logic High level at any specified address fusing a Ni-Cr link matrix. The N82S123N is widely used in Random logic and code conversion and so on.
