Product Preview  
64K x 4 Bit Static RAM  
The MCM6709BR is a 262,144 bit static random access memory organized as  
65,536 words of 4 bits. Static design eliminates the need for external clocks or  
timing strobes.  
J PACKAGE  
300 MIL SOJ  
CASE 810B–03  
Output enable (G) is a special control feature that provides increased system  
flexibility and eliminates bus contention problems.  
The MCM6709BR meets JEDEC standards and is available in a revolutionary  
pinout 300 mil, 28 lead plastic surface–mount SOJ package.  
PIN ASSIGNMENT  
Single 5 V ± 10% Power Supply  
Fully Static — No Clock or Timing Strobes Necessary  
All Inputs and Outputs are TTL Compatible  
Center Power and I/O Pins for Reduced Noise  
Three State Outputs  
Fast Access Times:  
MCM6709BR–6 = 6 ns  
MCM6709BR–7 = 7 ns  
MCM6709BR–8 = 8 ns
