SN74ABT5401DW

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT5401DW is an 11-bit buffer and line driver featuring 3-state outputs, manufactured by Texas Instruments in a 28-pin SOIC (DW) package. It 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. The device provides inverted data with high-level output current of -12 mA and low-level output current of 12 mA. Propagation delays are typically 4.4 ns for tPHL and 4.5 ns for tPLH at VCC = 5 V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the DW suffix denotes the plastic small-outline package. Confirm that the component meets the commercial temperature range specifications (-40°C to 85°C) rather than the military range associated with the SN54 variant. Ensure compatibility with the 4.5 V to 5.5 V supply voltage requirements during system design validation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an 11-bit wide interface is required for memory addressing or clock distribution. It is suitable for applications needing integrated series resistance to minimize signal reflections. Consider the dual active-low enable inputs for flexible control logic integration. Verify that the 12 mA drive capability aligns with the load requirements of the destination circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ABT family of BiCMOS logic devices, designed for high-speed digital applications. It differs from the SN54ABT5401 primarily in the operating temperature range, with the SN74 variant rated for commercial use. The device utilizes state-of-the-art EPIC-IIB BiCMOS design technology to significantly reduce power dissipation compared to older logic families.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN54ABT5401 is functionally identical but rated for the full military temperature range (-55°C to 125°C). Other 11-bit drivers in the ABT family may offer similar electrical characteristics but could differ in pinout or package options. Verify thermal impedance and package dimensions when substituting with alternative manufacturers' parts.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle the high-impedance state during power-up or power-down?

To ensure the high-impedance state during power-up or power-down, the OE input should be tied to VCC through a pullup resistor. The minimum value of this resistor is determined by the current-sinking capability of the driver.

What is the purpose of the internal series resistors in the outputs?

The outputs include equivalent 25-ohm series resistors designed to reduce overshoot and undershoot, eliminating the need for external resistors.
