QS7203-2OP

FIFOs Memory Overview

The QS7203-2OP 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, enabling high-speed data buffering operations. It is constructed using CMOS technology and is housed in a 28-pin PDIP package. The component operates with three-state outputs and includes full handshaking signals for reliable data transfer between asynchronous clock domains.

FIFOs Memory Feature Summary

• Asynchronous operation allows independent read and write clock domains
• Full handshaking interface ensures reliable data integrity during transfers
• CMOS construction provides low power consumption and high noise immunity
• Three-state outputs facilitate easy bus integration

FIFOs Memory Applications

• Data buffering between microprocessors and peripheral devices
• Interface bridging between systems operating at different clock speeds
• Temporary storage in digital signal processing pipelines
• Level shifting and synchronization in communication interfaces

FIFOs Memory Procurement Notes

Verify the specific suffix '2OP' to confirm the 20ns speed grade and PDIP package type. Ensure compatibility with existing board layouts requiring 28-pin through-hole mounting. Confirm voltage supply requirements match system specifications before integration. Check for RoHS compliance status if environmental regulations apply to the final assembly.

FIFOs Memory Selection Notes

Select this part when a 2Kx9 depth is required for asynchronous data buffering. The 20ns speed is suitable for moderate-frequency applications. Consider the PDIP package only if through-hole manufacturing processes are mandated. Compare against faster variants like the -12P or slower variants like the -50V based on timing constraints.

FIFOs Memory Part Context

The QS7203 series belongs to Quality Semiconductor's line of asynchronous FIFOs. This family offers various depths and speeds to suit different bandwidth requirements. The QS7203 specifically targets applications needing 18-bit wide data paths. It complements other members like the QS7204 which offers larger capacity.

FIFOs Memory Replacement Considerations

Direct substitutes include other QS7203 variants with compatible pinouts but different speeds, such as QS7203-12P or QS7203-35P. Verify that the replacement maintains the same 2Kx9 organization and PDIP-28 package form factor to ensure mechanical fit.
