Motorola, Inc. 1995
64K x 4 Bit Static RAM
The MCM6709A is a 262,144 bit static random access memory organized as
65,536 words of 4 bits, fabricated using high–performance silicon–gate BiCMOS
technology. Static design eliminates the need for external clocks or timing
strobes.
Output enable (G) provides increased system flexibility and eliminates bus
contention problems.
The MCM6709A is available in a 300 mil, 28 lead plastic surface–mount SOJ
package.
Single 5 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:
MCM6709A–8 = 8 ns
MCM6709A–10 = 10 ns
MCM6709A–12 = 12 ns
