Overview
The SN74AS850ADW is a high-speed 16-line to 1-line data selector and multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features TTL-compatible inputs with three-state outputs. The device utilizes Advanced Schottky (AS) technology to achieve high-speed performance, typically characterized by a propagation delay of 15ns. It is housed in a 28-pin Plastic Dual Small Outline (PDSO28) package, suitable for surface-mount applications.
Feature Summary
- Provides 16-line input selection capability for efficient data routing
- Features three-state outputs to facilitate bus-oriented systems
- Utilizes Advanced Schottky technology for high-speed operation
Applications
- Data processing systems requiring signal selection
- Arithmetic logic unit configurations
- Control systems utilizing bus-oriented architectures
Procurement Notes
Verify the specific datasheet version and package marking for the SN74AS850ADW to ensure compatibility with design requirements. Confirm that the 28-pin PDSO28 footprint matches the PCB layout. Check for any recent product change notifications regarding material composition or manufacturing site changes.
Selection Notes
Select this component when a high-speed 16-to-1 multiplexer with three-state outputs is required. Ensure the system operates within the specified 4.5V to 5.5V voltage range. Consider the 15ns typical propagation delay for timing analysis. Verify that the TTL input levels are compatible with the driving logic sources.
Part Context
This part belongs to the Texas Instruments SN74AS series, which represents Advanced Schottky logic family components known for superior speed-power trade-offs compared to standard Schottky devices. The SN74AS850 specifically addresses needs for high-performance data selection in digital circuits.
Replacement Considerations
Check for direct pin-compatible substitutes within the SN74AS series or other high-speed multiplexers from Texas Instruments. Verify electrical characteristics such as propagation delay and output drive strength against the original specifications.
