SN74ABT5400ADWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT5400ADWR is an 11-bit line and memory driver featuring 3-state outputs, manufactured by Texas Instruments. It utilizes state-of-the-art EPIC-IIB BiCMOS design to significantly reduce power dissipation while maintaining high performance. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. Outputs are designed to source or sink up to 12 mA and include equivalent 25-ohm series resistors to minimize signal overshoot and undershoot. Propagation delays typically range from 1.5 ns to 6.3 ns depending on the transition direction.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Integrated 25-ohm series output resistors eliminate the need for external components to reduce signal reflections.
• Dual active-low output enable inputs (OE1, OE2) function as a 2-input AND gate to control the high-impedance state.
• EPIC-IIB BiCMOS technology ensures low power consumption and robust latch-up protection exceeding 500 mA per JEDEC standards.

• Memory address drivers
• Clock drivers
• Bus-oriented receivers and transmitters

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DWR' corresponds to the SOIC-28 plastic package and tape-and-reel packaging configuration. Confirm that the component meets RoHS requirements if applicable to your assembly process. Ensure the datasheet revision matches your design specifications, as electrical characteristics may vary between revisions. Check for any specific handling instructions related to the BiCMOS technology used in this device.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 11-bit data paths with integrated termination resistors. It is suitable for applications needing reduced board space compared to discrete resistor solutions. Consider the 12 mA drive capability and 3-state functionality for bus sharing. Verify that the 4.5 V to 5.5 V supply voltage aligns with your system's power rails. Evaluate the propagation delay specifications against your timing requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN54/74ABT5400A family of 11-bit line/memory drivers. It is distinct from octal drivers like the SN74ABT540 due to its 11-bit width. The 'SN74' prefix indicates commercial temperature range operation, differentiating it from the military-grade SN54 variant. The 'DW' suffix denotes the Small-Outline package type.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements must match the 11-bit width and 3-state output configuration. Components like the SN74ABT540 are not direct substitutes due to differing bit counts. Verify pinout compatibility if substituting with other 28-pin logic drivers. Ensure the replacement supports the required 12 mA output current and similar propagation delays.
