SN74S225N3

Overview

The SN74S225N3 is a 16 x 5 asynchronous first-in, first-out (FIFO) memory device manufactured by Texas Instruments. It features 3-state outputs and is housed in a 20-pin PDIP package. The component operates within a temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous FIFO memory architecture for data buffering
• Three-state output capability for bus isolation
• Standard 20-pin PDIP packaging

Applications

• Data buffering between asynchronous systems
• Level conversion in digital circuits
• Temporary storage in microprocessor interfaces

Procurement Notes

Verify the specific suffix 'N3' against the manufacturer's current datasheet to confirm pinout and electrical specifications match your design requirements. Ensure the package type corresponds to your PCB footprint. Cross-reference with official Texas Instruments documentation to validate availability and lead times through authorized distributors.

Selection Notes

Select this component when an asynchronous 16-word by 5-bit memory buffer is required. Consider the 3-state outputs for system integration. Verify that the operating temperature range meets environmental conditions. Compare with synchronous alternatives if clock-domain crossing is necessary.

Part Context

This part belongs to the Texas Instruments SN74S series of logic components. It serves as a specialized memory element within the broader family of digital logic ICs, designed for specific data handling tasks rather than general-purpose logic operations.

Replacement Considerations

Check for direct replacements such as the SN74S225N. Verify compatibility with other 16x5 FIFO devices from different manufacturers only after confirming pinout and electrical parameter equivalence.
