• Cache Memory: Used in microprocessor and DSP systems to reduce memory access times.
• Buffer Memory: Provides temporary storage in data communication and signal processing applications.
• Control Store: Used in embedded systems to store microcode or control sequences.
• Graphics Display: Frame buffer for graphics cards and displays.
• Instrumentation: Used in test equipment and data acquisition systems for temporary data storage.

Features

• 16K x 4 Memory Organization: Offers a memory array of 16,384 words, each 4 bits wide.
• Fast Access Time: 45ns access time for rapid data retrieval.
• Low Power Consumption: Reduces overall system power requirements.
• Three-State Outputs: Allows for easy memory expansion and interfacing with other devices.
• Equal Access and Cycle Times: Simplifies system timing and control.
• DB Package: Ceramic DIP Package.

Benefits

• Improved System Performance: Fast access time reduces latency and speeds up data processing.
• Energy Efficiency: Low power consumption makes it suitable for battery-powered devices.
• Simplified Integration: Standard interface simplifies interfacing with microprocessors and other digital circuits.

Additional Details

The IDT7187L45DB operates from a single 5V power supply. The 45 in the part number indicates the access time in nanoseconds. The DB indicates the package type, which is a ceramic DIP package. The three-state outputs are controlled by an Output Enable (OE) pin. The chip enable (CE) input provides for easy memory selection. The operating temperature range is typically -55°C to +125°C, making it suitable for demanding environments.
