Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type against the ordering information table, as the 'D' suffix indicates a 20-pin plastic SO package. Confirm the temperature range matches the application requirements (-40°C to +85°C). Ensure compatibility with the 4.5V to 5.5V supply voltage range. Check for RoHS compliance status if required by the manufacturing process. Validate that the 30-ohm termination resistance aligns with the system's impedance matching needs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when driving bus lines requiring reduced line noise through integrated series termination. It is suitable for applications needing dual independent control groups of eight outputs. Consider the propagation delay specifications relative to the system clock speed. Evaluate the latch-up protection and ESD ratings for harsh environments. Compare the output drive capabilities (+12mA/-32mA) against the load requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

The 74ABT2241 belongs to the ABT logic family, known for high-speed operation and low power consumption. It is part of a broader range of octal buffers and transceivers designed for bus-oriented systems. The integration of series termination resistors distinguishes it from standard octal buffers, offering improved signal integrity in high-speed digital circuits without external components.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible substitutes within the same ABT family or other manufacturers offering octal buffers with similar termination characteristics. Verify that any replacement maintains the 30-ohm internal resistance value and 3-State output behavior. Ensure the alternative device supports the same voltage and temperature ranges.
