Product Summary

The MB84256C-70LL is a 32,768 word by 8-bit static random access memory fabricated with a CMOS silicon gate process. The memory utilizes asynchronous circuitry and may be maintained in any state for an indefinite period of time. All pins are TTL compatible, and a single +5V power supply is required. The MB84256C-70LL is ideally suited for use in microprocesser systems and other applications where fast access time and ease of use are required. The device offers the advantages of low power dissipation, low cost and high performance.
