描述 Description

The TC5117400BSJ/BST is the new generation dynamic RAM organized 4,194,304 word by 4 bits. The TC5117400BSJ/BST utilizes Toshiba’s CMOS silicon gate process technology as well as advanced circuit techniques to provide wide operating margins, both internally and to the system user. Multiplexed address inputs permit the TC5117400BSJ/BST to be packaged in a 26/24 pin plastic SOJ (300mil), and 26/24 pin plastic TSOP (300mil). The package size provides high system bit densities and is compatible with widely available automated testing and insertion equipment. System oriented features include single power supply of 5V± 10 tolerance, direct interfacing capability with high performance logic families such as Schottky TTL.
