SN74LS352N

Overview

The SN74LS352N is a dual 4-input multiplexer manufactured by Motorola, housed in a 16-pin DIP package. It functions as two independent 4-line to 1-line data selectors sharing common select inputs and featuring individual enable inputs for each multiplexer section. Designed for the LS TTL logic family, it operates with a single 5V power supply. The component supports digital signal routing and selection tasks within legacy systems.

Feature Summary

• Dual independent 4-to-1 multiplexing capability
• Shared select input lines for synchronized channel switching
• Individual enable inputs for precise control of each multiplexer section

Applications

• Digital signal routing in legacy computer systems
• Data selection circuits requiring multiple input sources
• Logic design utilizing shared address decoding

Procurement Notes

Verify RoHS compliance status, as this specific variant may not meet current environmental directives. Confirm package integrity and pin configuration upon receipt. Check for New Old Stock (NOS) designation when sourcing from distributors. Ensure compatibility with existing LS TTL voltage levels and interface requirements before integration into modern designs.

Selection Notes

Select this component when dual independent 4:1 multiplexing with shared addressing is required within an LS TTL environment. Consider the 16-pin DIP form factor for through-hole mounting constraints. Evaluate availability due to potential discontinuation or limited production runs compared to newer CMOS alternatives.

Part Context

This device belongs to the standard 74LS series of high-speed TTL logic components. It provides a reliable solution for analog/digital signal switching applications where low power consumption relative to earlier TTL families is necessary. The dual structure allows efficient use of board space for multi-channel selection tasks.

Replacement Considerations

Cross-reference with other manufacturers' SN74LS352 equivalents such as those from Texas Instruments or NXP. Verify pinout compatibility and electrical characteristics match before substitution. Note that some variants may have different suffixes indicating temperature ranges or packaging types.
