Frequently Asked Questions
What is the SN74AS756DW and what does it do?
The SN74AS756DW is an octal (8-bit) buffer and line driver with 3-state outputs from Texas Instruments' Advanced Schottky logic family. It is designed to buffer and drive signals on data buses, allowing multiple devices to share a common bus line without signal contention. Its 3-state outputs can be disabled to effectively disconnect the driver from the bus.
What package does the SN74AS756DW come in and what are its pin dimensions?
The SN74AS756DW comes in a DW package, which is a 20-pin wide SOIC (Small Outline Integrated Circuit) surface-mount package. This package is well-suited for automated PCB assembly and offers a compact footprint while maintaining good thermal and electrical performance in high-speed digital designs.
What are typical applications for the SN74AS756DW?
Typical applications for the SN74AS756DW include microprocessor data bus buffering, memory interface driving, industrial control bus interfaces, and any system requiring high-speed 8-bit logic signal buffering. The Advanced Schottky technology ensures fast propagation times, making it suitable for demanding digital logic environments where timing is critical.
How does the SN74AS756DW compare to other 74AS series bus drivers?
The SN74AS756DW is part of TI's 74AS (Advanced Schottky) logic family, offering faster switching speeds than standard 74LS or 74S devices. Compared to CMOS-based alternatives like the 74HC244, the AS series provides lower propagation delay and is optimized for TTL-compatible systems. It is pin and function compatible with other octal buffer ICs in the 74x756 family.
