32K x 8 Bit Static Random
Access Memory
The MCM6706CR is a 262,144 bit static random access memory organized
as 32,768 words of 8 bits. Static design eliminates the need for external clocks
or timing strobes.
Output enable (G) is a special control feature that provides increased system
flexibility and eliminates bus contention problems.
The MCM6706CR meets JEDEC standards and is available in a revolutionary
pinout 300 mil, 32–lead surface–mount SOJ package.
• Single 5.0 V ± 10% Power Supply
• Fully Static — No Clock or Timing Strobes Necessary
• All Inputs and Outputs Are TTL Compatible
• Three State Outputs
• Fast Access Times: MCM6706CR–5 = 5 ns
MCM6706CR–5.5 = 5.5 ns
• Center Power and I/O Pins for Reduced Noise
