NEe Microcomputers, Inc. 4098-BIT BIPOLAR TTL PROGRAMMABLE READ ONLY MEMORY NEe JLPB406 JLPB426 JLPB406-1 JLPB426-1 JL PB406-2 JL PB426-2 DESCRIPTION The IlPB406 and IlPB426 are high-speed, electrically programmable, fully-decoded 4096-bit TTL read-only memories. On-chip address decoding, two chip·enable inputs and open-collector/three-state outputs allow easy expansion of memory capacity. The IlPB406 and IlPB426 are fabricated with logic level zero (low); logic level one (high) can be electrically programmed into the selected bit locations. The same address inputs are used for both programming and reading. FEATURES • 1024 WORD X 4 BIT Organization (Fully Decoded) • TTL Interface • Fast Read Access Time: 50 ns max. (IlPB406-2, IlPB426·2) • Medium Power Consumption: 500 mW TYP.
