What are the key features of SN74ABT5400ADWE4?

  • ABT-family unidirectional bus driver with dual output enable
  • Active-low enable control for flexible bus arbitration
  • 50 pF rated load capacitance for backplane driving
  • 12 mA maximum low-level output current (I_OL)
  • 28-pin SOIC package for standard SMT assembly
  • RoHS-compliant lead-free Green plastic construction

What is SN74ABT5400ADWE4 used for?

SN74ABT5400ADWE4 is used in digital system backplane designs where multiple board-to-board data buses require high-speed, actively controlled buffering with dual independent enable signals. It suits address and data bus drivers in processor-based systems, industrial computers, and network switching hardware where ABT logic levels ensure compatibility with 5 V TTL and 3.3 V CMOS mixed-supply environments. The dual output enable feature simplifies bus sharing between multiple masters without external glue logic.

Frequently Asked Questions

How does the dual output enable on SN74ABT5400ADWE4 simplify multi-master bus designs?

SN74ABT5400ADWE4 includes 2 independent active-low output enable inputs, allowing designers to implement bus arbitration directly at the driver level without additional logic gates. Each enable controls a subset of the 28-pin output lines, enabling flexible bus partitioning in multi-master backplane architectures.

What load capacitance rating does SN74ABT5400ADWE4 support and what does this mean for backplane trace lengths?

SN74ABT5400ADWE4 is rated for a load capacitance of 50 pF, which corresponds to moderate-length backplane traces or short ribbon cable connections at typical ABT switching speeds. For longer traces or heavier capacitive loads, signal integrity analysis is recommended to confirm rise-time and propagation delay margins.

Is SN74ABT5400ADWE4 still available for new designs given its YTEOL rating?

SN74ABT5400ADWE4 shows a YTEOL value of 0, indicating it is at end-of-life and is not recommended for new designs. Engineers should source remaining inventory for existing production or evaluate current ABT or LVC family bus drivers from Texas Instruments with equivalent 28-pin SOIC pinout and dual enable functionality.

What output current does SN74ABT5400ADWE4 provide and how does it compare to standard 74HC bus drivers?

SN74ABT5400ADWE4 has a maximum low-level output current (I_OL) of 12 mA per output, higher than typical 74HC parts which are rated at 4 mA to 8 mA. This additional drive strength is useful for driving multiple receiving inputs or longer PCB traces with tight timing budgets in high-speed bus designs.
