Product Summary

The N82S131N is a 2k-bit TTL bipolar PROM, which means that custom patterns are immediately available by following the Signetics generic I fusing procedure. The applications of the N82S131N are prototyping/volume production, sequential controllers, microprogramming, hardwired algorithms, control store, random logic and code conversion.
