Plastic Packages:
P-SOJ-40-1 400mil width
The HYB 314171BJ/BJL is a 4 MBit dynamic RAM organized as 262 144 words by 16-bit. The
HYB 314171BJ/BJL 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 314171BJ/BJL to be packed in a standard plastic 400mil 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 Self Refresh (L-
Version), single + 3.3 V (鹵 0.3 V) power supply, direct interfacing with high performance logic
device families.
