QS7202-12JR

FIFOs Memory Overview

The QS7202-12JR is an asynchronous FIFO memory integrated circuit manufactured by Quality Semiconductor. It features a memory organization of 1K x 9 bits, providing a total capacity of 9 kilobits. The device operates within a commercial temperature range of 0°C to 70°C. It is housed in a 14-pin Ceramic Dual In-Line Package (CDIP) with a standard 0.300-inch (7.62mm) width. This component is designed for high-speed data buffering applications requiring independent read and write clock domains.

FIFOs Memory Feature Summary

• Asynchronous operation allowing independent read and write clock domains
• High-speed data buffering capability for logic interfaces
• Robust ceramic dual in-line package construction

FIFOs Memory Applications

• Data buffering between asynchronous digital systems
• Interface bridging in computer peripheral systems
• Signal processing data storage stages

FIFOs Memory Procurement Notes

Verify the manufacturer designation carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the part number matches the specific Quality Semiconductor variant. Confirm the package type is the 14-CDIP ceramic version. Check for obsolescence status and source from authorized distributors to guarantee authenticity and avoid counterfeit components.

FIFOs Memory Selection Notes

Select this component when asynchronous FIFO functionality with a 1Kx9 organization is required. The ceramic package offers superior thermal and mechanical stability compared to plastic variants. Consider the operating temperature range of 0°C to 70°C for environmental compatibility. Verify pinout compatibility if replacing existing designs.

FIFOs Memory Part Context

The QS7202 series belongs to the family of asynchronous FIFO memories. Quality Semiconductor produced these components before industry consolidations involving National Semiconductor. The device serves as a bridge for data transfer between systems operating at different clock speeds or phases.

FIFOs Memory Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-reference compatibility with other 1Kx9 asynchronous FIFOs from current manufacturers.
