HYB 5117400BJ/BT-50/-60/-70
4M x 4-DRAM
The HYB 5117400BJ/BT is a 16MBit dynamic RAM organized as 4194304 words by 4-bits. The
HYB 5117400BJ/BT 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 5117400BJ/BT to be packaged in a standard SOJ
26/24 or TSOPII-26/24 plastic package, both with 300 mil width. 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.
