DESCRIPTION

The TCs142s6P/J/Z is the new generation dynamic RAM organized 262,144 words by 4

bit. The TCs142s6P/J/Z 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 TCs142s6P/J/Z to be packaged in a

standard 20 pin plastic DIP and 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. System oriented features include single power

supply of 5V±10 tolerance, direct interfacing capability with high performance logic

families such as Schottky TTL.
