512K x 8 Bit Static Random
Access Memory
The MCM6946/SCM6946 is a 4,194,304–bit static random access memory or-
ganized as 524,288 words of 8 bits. Static design eliminates the need for external
clocks or timing strobes.
The MCM6946/SCM6946 is equipped with chip enable (E) and output enable
(G) pins, allowing for greater system flexibility and eliminating bus contention
problems. Either input, when high, will force the outputs into high impedance.
The MCM6946 is available in a 400 mil, 36–lead surface–mount SOJ package.
Single 3.3 V – 5%, + 10% Power Supply
Fast Access Time: 8/10/12/15 ns
Equal Address and Chip Enable Access Time
All Inputs and Outputs are TTL Compatible
Three–State Outputs
Power Operation: 195/185/180/175 mA Maximum, Active AC
Available in TSOP or SOJ Packages
