Description
The GS74108 is a high speed CMOS static RAM organized as
524,288-words by 8-bits. Static design eliminates the need for exter-
nal clocks or timing strobes. Operating on a single 3.3V power supply
and all inputs and outputs are TTL compatible. The GS74108 is avail-
able in 400 mil SOJ and 400 mil TSOP Type-II packages.
