QS7201-25V

FIFOs Memory Overview

The QS7201-25V is an asynchronous FIFO memory device manufactured by Quality Semiconductor. It features a memory organization of 512 words by 9 bits, providing a total density of 4608 bits. The component supports a maximum access time of 25 nanoseconds with a cycle time of 35 nanoseconds. It operates within a supply voltage range of 4.5 V to 5.5 V and utilizes CMOS technology. The device is housed in a 28-pin Small Outline (PDSO28) package.

FIFOs Memory Feature Summary

• Asynchronous operation mode for flexible data buffering
• CMOS technology ensuring low power consumption
• Parallel interface architecture
• Totem pole output structure

FIFOs Memory Applications

• Data buffering between different speed domains
• Level shifting in digital systems
• Temporary storage in high-speed data acquisition

FIFOs Memory Procurement Notes

Verify the specific suffix 'V' indicates the 28-pin small outline package variant. Confirm the manufacturer as Quality Semiconductor Inc or its successor entities. Check for obsolete status indicators as this part may be discontinued. Ensure compatibility with 5V logic levels before integration into new designs.

FIFOs Memory Selection Notes

Select this component when a 512x9 asynchronous FIFO is required with 25ns access speed. Compare against synchronous alternatives if clock alignment is necessary. Consider the 28-pin SOIC package constraints for PCB layout. Verify temperature range requirements against commercial specifications.

FIFOs Memory Part Context

This part belongs to the QS7201 family of asynchronous FIFOs from Quality Semiconductor. Variants such as QS7201-80J offer slower speeds but similar capacities. The family provides parallel data transfer capabilities for system integration. Different suffixes denote package types and speed grades within the same functional architecture.

FIFOs Memory Replacement Considerations

QS7201-25JR is a ceramic chip carrier variant with identical electrical characteristics. QS7201-50V offers a slower 50ns access time but maintains the same pinout and functionality. Cross-reference with IDT equivalents if Quality Semiconductor parts are unavailable.
