Product Details
__
The HYB 514256B/BJ/BL/BJL is the new generation dynamic RAM organized as 262 144 words by 4-bit. The HYB 514256B/BJ/BL/BJL utilizes 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 514256B/BJ/BL/BJL to be packaged in a standard plastic P-DIP-20-2,or plastic P-SOJ-26/20-1. 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. These HYB 514256BL/BJL are specially selected for battery backup applications.
