Features
• Fast access time: 8, 10, 12 ns
• CMOS low power operation: 120/95/85 mA at minimum
• Single 3.3 V power supply
• All inputs and outputs are TTL-compatible
• Fully static operation
• Industrial Temperature Option: –40° to 85°C

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.
Pin Descriptions
*All GSI Technology packages are at least 5/6 RoHS compliant.
Packages listed with the additional “G” designator are 6/6 RoHS compliant.
Rev: 1.07 1/2006
