Features
• Fast access time: 8, 10, 12, 15 ns
• CMOS low power operation: 150/125/110/90 mA at
• Single 3.3 V ± 0.3 V power supply
• All inputs and outputs are TTL-compatible
• Fully static operation
• Industrial Temperature Option: –40° to 85°C
• Package line up
Description
The GS72108 is a high speed CMOS Static RAM organized as
262,144 words by 8 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-com-
patible. The GS72108 is available in 400 mil SOJ and 400 mil
TSOP Type-II packages.
