S-!!IDotiCS 82S126 1024-B11 BIPOLAR 82S129 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _P_RO_GRA_M_MA_BL_ER_OM_(2_56_x4_PR_OM~) FEBRUARY 1975 DIGITAL 8000 SERIES TTL/MEMORY DESCRIPTION The 82S126 (Open Collector Outputs) and the 82S129 (Tri-State Outputs) are Bipolar 1024-Bit Read Only Memories, organized as 256 words by 4 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 82S 126 and 82S 129 devices are supplied with all outputs at logical "0". Outputs are programmed to a logic "1" level at any specified address by fusing a Ni-Cr link matrix. The 82S126 and 82S129 are fully TTL compatible, and include on-chip decoding and two chip enable inputs for ease of memory expansion.
