The MD2114A-4/B is a 1024 x 4 bit static RAM (SRAM) manufactured by various companies, including a re-creation by Rochester Electronics. As a recreated device, Rochester ensures it meets the original manufacturer's specifications and performance characteristics. The MD2114A family of SRAMs are known for their relatively fast access times and ease of use in various memory applications.

Applications

• Microprocessor-based systems
• Embedded systems
• Data buffering
• Cache memory
• Industrial control equipment

Features

• 1024 x 4 bit organization
• Fast access time (typically 450ns)
• Static operation (no refresh required)
• TTL compatible inputs and outputs
• Single +5V power supply
• Three-state outputs

Benefits

• Easy to interface with microprocessors
• Simple memory system design
• High-speed data access
• Reliable data storage
• Long-term availability (through Rochester Electronics)

Additional Details

The MD2114A-4/B requires a single +5V power supply for operation. The access time of 450ns refers to the maximum time required for the data to be valid after the address lines are stable. The three-state outputs allow multiple memory devices to be connected to a common data bus. The static operation means that the data is retained as long as power is applied; no refresh cycles are needed. Rochester Electronics ensures that their recreated MD2114A-4/B parts meet or exceed the original specifications, providing a reliable source for legacy systems and applications. The '/B' suffix might indicate a slightly different timing or temperature range compared to the standard MD2114A-4 part. Datasheets from Rochester Electronics provide the specific details for their manufactured version.
