82S123
DESCRIPTION The 82S23 (Open Collector Outputs) and the 82S123 (Tri-State Outputs) are Bipolar 256-Bit Read Only Memories, organized as 32 words by 8 bits per word. They are Field-Programmable~ which means that custom patterns are immediately available by following the fusing procedure given in th is data sheet. The standard 82S23 and 82S 123 devices are supplied with all outputs at logical "0". Outputs are programmed to a logic "1" level at any specified address by fusing a N i-Cr link matrix. The 82S23 and 82S123 are fully TTL patible, and include on-chip decoding and one chip enable input for ease of memory expansion. They feature either Open Collector or Tri-State outputs for optimization of word expansion in bussed organizations. Both 82S23 and 82S123 devices are available in the mercial and military temperature ranges. For the mercial temperature range (Do C to + 75°C) specify N82S23/123, B or F. For the military temperature range (-55°C to +125°C) specify S82S23/123, F...
