Description
The GS74117A is a high speed CMOS Static RAM organized
as 262,144 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 GS74117A is available in a 6 x 10 mm Fine
Pitch BGA package.
