DESCRIPTION

The TC5164(5)405BJ/BFT/BJS/BFTS is an EDO (hyper page) dynamic RAM organized as 16,777,216

words by 4 bits. TC5164(5)405BJ/BFT/BJS/BFTS 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 TC5164(5)405BJ/BFT/BJS/BFTS to be

packaged in either a 32-pin plastic SOJ or a 32-pin plastic TSOP. The package size provides high

system bit densities and is compatible with widely available automated testing and insertion

equipment. Other features include a single power supply of 3.3V±0.3V tolerance and direct interfacing

with high performance logic families such as LVTTL.
