Overview
The SN74AS352N is a dual 4-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It belongs to the AS (Advanced Schottky) logic family, designed for high-speed digital applications requiring TTL compatibility. The device integrates two independent multiplexers within a single package, allowing efficient routing of multiple input signals to a common output line based on select inputs.
Feature Summary
- Integrates two independent 4-to-1 multiplexers in a single package
- Compatible with standard TTL logic voltage levels
- Utilizes Advanced Schottky technology for enhanced switching speed
Applications
- Digital signal routing systems
- Data selection circuits
- Multiplexing interfaces in TTL-based systems
Procurement Notes
Verify the exact suffix 'N' indicates the specific package type and temperature rating. Confirm datasheet revisions match your design requirements. Ensure supply chain sources provide original manufacturer documentation to avoid counterfeit components. Cross-reference pinouts with official Texas Instruments schematics before integration.
Selection Notes
Select this component when dual independent multiplexing is required within a TTL-compatible environment. The AS series offers faster propagation delays compared to standard LS or ALS families. Evaluate power consumption constraints as AS logic typically draws more current than low-power variants but provides superior speed performance for critical timing paths.
Part Context
This part is part of the broader SN74xx series of logic ICs from Texas Instruments. It serves as a specialized variant within the AS family, focusing on multiplexing functions rather than buffering or inversion. It complements other AS-series components like buffers and inverters in complex digital system designs.
Replacement Considerations
Check for SN74ALS352N or SN74LS352N if speed requirements are less stringent. Verify pinout compatibility with SN74F352N for potential upgrades. Ensure substitute parts maintain the same dual 4-to-1 multiplexer functionality and TTL input thresholds.
