MB81C78A-351-45 CMOS 64K-BIT HIGH-SPEED SRAM
8K Words x 8 Bits High-Speed CMOS Static Random Access Memory with Automatic Power Down
The FujHsu MB81C78A is a 8,192 words x 8 bits static random access memory fabricated with a CMOS process. The memory uses asynchronous circuHry and may be maintained in any state for an indefinite period of time. All pins are TTL patible and a single +5 V power supply is required.
A separate chip select (CS1) pin simplifies mu~ipackage systems design by permHing the selection of an individual package when outputs are OR-tied, and then automatically powering down the other deselected packages.
