256k × 16-Bit EDO-DRAM

The HYB 514175BJ is the new generation dynamic RAM organized as 262 144 words by 16-bit. The HYB 514175BJ utilizes CMOS silicon gate process as well as advanced circuit techniques to provide wide operation margins, both internally and for the system user. Multiplexed address inputs permit the HYB 514175BJ to be packed in a standard plastic 400 mil wide P-SOJ-40-1 package. This package size provides high system bit densities and is compatible with commonly used automatic testing and insertion equipment. System oriented features include single + 5 V (± 10 ) power supply, direct interfacing with high performance logic device families such as Schottky TTL.
