Features
• Fast access time: 8, 10, 12, 15ns
• CMOS low power operation: 150/125/110/90 mA at min. cycle time.
• Single 3.3V ± 0.3V power supply
• All inputs and outputs are TTL compatible
• Fully static operation
• Industrial Temperature Option: -40° to 85°C
• Package line up
Description
The GS74108 is a high speed CMOS static RAM organized as
524,288-words by 8-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 GS74108 is avail-
able in 400 mil SOJ and 400 mil TSOP Type-II packages.
