256K x 4 Bit Fast Static Random
Access Memory
The MCM6729C is a 1,048,576 bit static random access memory organized
as 262,144 words of 4 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.
This device meets JEDEC standards for functionality and revolutionary pinout,
and is available in a 400 mil plastic small–outline J–leaded 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: 6, 7 ns
Center Power and I/O Pins for Reduced Noise
