Description
The GS74108A is a high speed CMOS Static RAM organized
as 524,288 words by 8 bits. Static design eliminates the need
for external clocks or timing strobes. The GS74108A operates
on a single 3.3 V power supply and all inputs and outputs are
TTL-compatible. The GS74108A is available in 400 mil SOJ,
400 mil TSOP-II, and 6 mm x 10 mm FPBGA packages.
