Frequently Asked Questions
What is the SN74ABT8543DW and what does it do?
The SN74ABT8543DW is an octal bus transceiver with 3-state outputs from Texas Instruments. It provides bidirectional data transfer between two 8-bit buses, controlled by direction (DIR) and output-enable (OE) pins, making it ideal for buffering and isolating data buses in digital systems.
What logic family does the SN74ABT8543DW belong to?
The SN74ABT8543DW belongs to Texas Instruments' ABT (Advanced BiCMOS Technology) logic family. ABT devices combine bipolar and CMOS technologies to deliver fast propagation delays, typically under 5 ns, while maintaining low quiescent power consumption and TTL-compatible input/output levels.
What package does the SN74ABT8543DW use?
The SN74ABT8543DW uses a 24-pin SOIC (Small Outline Integrated Circuit) wide-body package, denoted by the 'DW' suffix. This surface-mount package has a 7.5 mm body width and 1.27 mm pin pitch, suitable for automated PCB assembly and compact board designs.
What are typical applications for the SN74ABT8543DW?
Typical applications include bidirectional data bus buffering in computer motherboards, embedded processor systems, memory interfaces, industrial control PLCs, and backplane interconnects. The 3-state outputs allow multiple transceivers to share a common bus without contention, making it suitable for any shared-bus or multi-master architecture.
Where can I buy the SN74ABT8543DW and what is the price?
