QS7203-20JR

FIFOs Memory Overview

The QS7203-20JR is an asynchronous FIFO memory integrated circuit manufactured by Quality Semiconductor. It features a memory organization of 2K x 9 bits, providing a total capacity of 18 kilobits. The device supports a maximum access time of 20 nanoseconds and operates with a 5V power supply. It is housed in a 28-pin plastic dual in-line package (PDIP) or surface-mount variant depending on the specific suffix, designed for high-speed data buffering applications requiring reliable asynchronous operation.

FIFOs Memory Feature Summary

• Asynchronous operation mode for flexible data transfer between clock domains
• CMOS technology ensuring low power consumption and high noise immunity
• Dedicated full and empty status flags for precise buffer management
• Wide 9-bit data width suitable for parallel data bus interfacing

FIFOs Memory Applications

• Data buffering in telecommunications equipment
• Interface bridging between microprocessors and peripheral devices
• High-speed data acquisition systems
• Industrial control system data logging

FIFOs Memory Procurement Notes

Verify the exact package type and pinout configuration against your PCB design requirements, as suffixes may indicate different physical footprints. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the 5V operating voltage matches your system's logic levels. Check for obsolescence notices from the manufacturer before finalizing procurement plans.

FIFOs Memory Selection Notes

Select this component when a 2Kx9 depth and 20ns speed are required for asynchronous data buffering. Compare against similar FIFOs if higher density or faster speeds are needed. Consider the 9-bit width compatibility with your data bus architecture. Evaluate thermal performance within the specified operating temperature range for your specific application environment.

FIFOs Memory Part Context

This part belongs to the QS7203 series of asynchronous FIFOs from Quality Semiconductor. The series typically includes variants with different access times and packaging options. These components are designed for general-purpose data storage and synchronization tasks in digital electronics, offering a balance of speed and capacity for embedded systems.

FIFOs Memory Replacement Considerations

Direct substitutes include other 2Kx9 asynchronous FIFOs with comparable 20ns access times. Verify pin compatibility and electrical specifications before substitution. Alternative packages such as SOIC or PLCC may require adapter solutions if the original PDIP form factor is unavailable.
