What are the key features of SN74ABT573ADWG4?

  • Octal 3-state transparent D-latch with active-low output enable for direct bus interface and data buffering in 8-bit wide data paths
  • ABT logic family delivers high-speed switching with 50pF load capacitance rating and 64mA output sink current for robust bus driving
  • Broadside pinout version of the industry-standard 373 latch simplifies PCB routing in bus-oriented designs
  • 3-state outputs allow multiple devices to share a common bus without contention in multiplexed data bus architectures

What is SN74ABT573ADWG4 used for?

The SN74ABT573ADWG4 is used as a transparent data latch and bus driver in address and data bus buffering for microprocessor and DSP systems in industrial and communications equipment. Its high output current and 3-state capability make it ideal for driving data buses between memory, I/O peripherals, and processor banks in embedded systems requiring fast, reliable data latching. The device is also suitable for register interfacing in FPGA and CPLD designs where bus direction control and data hold capability are required.

Frequently Asked Questions

Which design use cases are a practical fit for SN74ABT573ADWG4?

SN74ABT573ADWG4 is a Integrated Circuit from Texas Instruments suited to embedded systems, industrial electronics, communication equipment, test fixtures, and production BOM sourcing. The 20 pins detail helps engineers confirm schematic fit, interface allocation, and sourcing suitability before BOM approval.

How should engineers check package compatibility for SN74ABT573ADWG4 during layout review?

Use the Small Outline Packages package information together with 20 pins when comparing footprints, assembly drawings, and mating or socket constraints. This reduces layout risk before prototype or production purchasing.

What should procurement keep aligned when cross-referencing SN74ABT573ADWG4 against alternates?

Cross-reference checks should preserve the manufacturer, Integrated Circuit function, package style, lifecycle status, and at least one key parameter such as -40°C to 85°C. Matching these details lowers substitution risk across 1 approved BOM.
