• Provides selectable timing modes including First-Word Fall-Through (FWFT) and standard operation.
• Includes programmable almost-empty and almost-full flags with configurable offset thresholds.
• Features independent read and write clocks allowing simultaneous data operations.

FIFOs Memory Applications

• Network buffering applications
• Video signal processing systems
• Telecommunications equipment
• Data communications interfaces

FIFOs Memory Procurement Notes

Verify the specific ordering suffix matches the required package variant and temperature rating. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly process specifications. Ensure the datasheet revision aligns with your design documentation. Check for any product change notifications that may affect pinout or electrical characteristics prior to finalizing procurement orders.

FIFOs Memory Selection Notes

Select this component when deep memory depth and high-speed synchronous operation are required. Consider the SN74V293 for designs needing flexible bus width adaptation between different system components. Evaluate the available flag outputs and retransmit capabilities against your specific data handling logic requirements before choosing over other FIFO variants.

FIFOs Memory Part Context

This part belongs to the SN74V293 series of high-speed CMOS FIFO memories from Texas Instruments. The series includes variants with different memory depths such as the SN74V263, SN74V273, and SN74V283. All members share similar architectural features but differ in storage capacity and maximum operating frequencies based on their specific model designation.
