Description
The GS74116 is a high speed CMOS static RAM organized as
262,144-words by 16-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 GS74116 is avail-
able in a 7.2x11.65 mm Fine Pitch BGA package, 400 mil SOJ and
400 mil TSOP Type-II packages.
