DESCRIPTION
The TC514256AP/AJ/AZ is the new generation dynamic RAM organized 262,144 words by 4 bits.
The TC514256AP/AJ/AZ 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 TC514256AP/AJ/AZ to be packaged in a standard 20 pin plastic
DIP, 26/20 pin plastic SOJ and 20/19 pin plastic ZIP. The package size provides high system bit
densities and is compatible with widely available automated testing and insertion equipment.
oriented features include single power supply of 5V±10 tolerance, direct interfacing capability with
high performance logic families such as Schottky TTL.
