Description
The GS72108 is a high speed CMOS Static RAM organized as
262,144 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 GS72108 is available in 400 mil SOJ and 400 mil
TSOP Type-II packages.
