32K x 8 Bit Static Random
Access Memory
The MCM6706B 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 MCM6706B is available in a 300 mil, 28–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: MCM6706B–8 = 8 ns
MCM6706B–10 = 10 ns
MCM6706B–12 = 12 ns
