Ground
The GS78116A is a high speed CMOS Static RAM organized
as 524,288-words by 16-bits. Static design eliminates the need
for external clocks or timing strobes. The GS78116A operates
on a single 3.3 V power supply, and all inputs and outputs are
TTL-compatible. The GS78116 is available in a
14 mm x 22 mm BGA package.

• Fast access time: 8, 10, 12 ns
• CMOS low power operation: 240/190/170 mA at minimum
cycle time
• 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
• 14 mm x 22 mm, 119-bump, 1.27 mm Pitch Ball Grid Array
