Description
The GS71208 is a high speed CMOS Static RAM organized as
131,072 words by 8 bits. Static design eliminates the need for
external clocks or timing strobes. The GS operates on a single
3.3 V power supply and all inputs and outputs are TTL-com-
patible. The GS71208 is available in a 400 mil TSOP Type-II
package.
