The HYB 5117800BSJ utilizes a submicron CMOS silicon gate process technology, as well as advanced circuit techniques to provide wide operating margins, both internally and for the system user. Multiplexed address inputs permit the HYB 5117800BSJ to be packaged in a standard SOJ 28 400 mil plastic package. These packages provide high system bit densities and are 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.
