Product Summary

The 82S23 is a 256-bit TTL bipolar PROM. Custom patterns are immediately available by following the Signetics Generic I fusing procedure. The 82S23 and 82S123 devices are supplied with all outputs at logical Low. Outputs are programmed to a logic High level at any specified address by fusing the Ni-Cr link matrix. Its applications include Prototyping/volume production, Sequential controllers, Format conversion, Hardwired algorithms, Random logic.
