GM71C(S)17400C/CL
4,194,304 WORDS x 4 BIT CMOS DYNAMIC RAM
Description
The GM71C(S)17400C/CL is the new generation dynamic RAM organized 4,194,304 w o r d s x 4 bit. GM71C(S)17400C/CL has realized higher density, higher performance and various functions by utilizing advanced CMOS process technology. The GM71C(S)17400C/CL offers Fast Page Mode as a high speed access mode. Multiplexed address inputs permit the G M 7 1 C ( S ) 1 7 4 0 0 C / C L to be packaged in a standard 300 mil 24(26) pin SOJ, and a standard 3 0 0 mil 24(26) pin plastic TSOP II. The package size provides high system bit densities a n d is compatible with widely available a u t o m a t e d testing and insertion equipment. System oriented features include single power supply 5.0V+/-10% tolerance, direct interfacing capability with high performance logic families such as Schottky TTL.
