Description
The GS72116A is a high speed CMOS Static RAM organized
as 131,072 words by 16 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-
compatible. The GS72116A is available in a 6 mm x 8 mm
Fine Pitch BGA and 400 mil TSOP Type-II packages.
